Dennis Keeler: yes
Tepper Gill: yes
Regina Souza: is it time to activate the VNC viewer?
9:50 AM
Mike May: Harry, Maple is running on ione machine, Shared Server Maple is running off a 
server. The right answer depends on your setrup
Mike May: Harry , I suspect you want Maple
Harry Mills: Yeah, that's what i figured.
Mike May: We are doing fairly well for the first morning. All but 4 participants are in the 
chat.
Dennis Keeler: Is the VNC server running yet? I'm getting a Could not connect to server 
165.134.131.152:5900 Operation timed out: connect()
Mike May: I think that is very good 10 minutes in advance.
Derrick Head: What is the URL for Quicktime?
Matt Goeke: You have the wrong address for the VNC. The VNC address is 
165.134.131.96 on port 5900 if needed
Mike May: We are changing tapes so the video is stopping.
Dennis Keeler: OK, working now.
Harry Mills: Just lost video.
Harry Mills: Oh... Duh.
Hugh Sanders: Should the video say Stand By
Matt Goeke: URL for QT is 165.134.270.35/LA050627am1.sdp
9:55 AM
Matt Goeke: rtsp://165.134.240.35/LA050627am1.sdp- copy and paste into the Quicktime 
URL window
Matt Goeke: sorry about that.
Mike May: The new url will bertsp://165.134.240.35/LA050627am1.sdp
Leah Wrenn Berman: Are these addresses valid for the rest of the conference? (Should I 
save them?)
Mike May: Remember to cut and paste ratehr than double click
Mike May: The videos will change every 20-25 minutes
Mike May: The urls for the videos will have a pattern,
David Huckaby: Have we addressed the problem of VNC closing when you try to copy and 
paste?
Leah Wrenn Berman: if you use command-w in Maple 10 it closes the document but not 
the program
Leah Wrenn Berman: at leats on the mac version
David Huckaby: I just did (to start Quicktime) and VNC of course closed.
Mike May: the dates are yymmdd and we will have am1, am2, am3, am4

Luz DeAlba: OK
Parviz Khalili: Have started the video yet?
Russell Blyth: yes
Harry Mills: I'm getting sound thru the video, but the picture's messed up. Main thing is the 
sound, anyway.
10:00 AM
Russell Blyth: rtsp://165.134.240.35/LA050627am1.sdp
Mike May: Video is started
Michael Siddoway: Should I see you Mike
Parviz Khalili: I can see you guys and sound fine.
Michael Siddoway: ?
Russell Blyth: MS?
Hugh Sanders: Is there a video movie with sound that is running now?
Michael Siddoway: Mike Sidd? Yep
Russell Blyth: Yes, video running at the address above
Laurel Cooley: I can hear you, but the QT screen is green
Russell Blyth: MS,OK?
Matt Goeke: JQuella - What version of VNC software are you using?
Michael Siddoway: Where do we paste the address?
John Boncek: Russell -- Jack in Montgomery. VNC is fine. Quicktime -- as it was last 
week midweek. 
Russell Blyth: In File menu, Open URL ...
Laurel Cooley: You are still all green
Russell Blyth: Does anyone have any problems?
Russell Blyth: Other than LC?
Laurel Cooley: I can't see you, the QT screen is all green
Christian Hellings: Can you send the VNC address again?
Michael Siddoway: "File" Menu on this window?
Russell Blyth: VNC 165.134.131.96
Laurel Cooley: Yes, I can hear you.
Russell Blyth: Fiole menu in Quicktime
Russell Blyth: File
Mike May: Quicktimertsp://165.134.240.35/LA050627am1.sdp Quicktime
Marius Buliga: everything is fine here.
Mike May: vnc 165.134.131.96
Parviz Khalili: The video is frozen now!
Dennis Keeler: video frozen for me too, on a Mac. Audio still OK.
Russell Blyth: Anyone else?How is audio?
John Boncek: audio OK. green screen video. VNC ok
Harry Mills: Visual frozen, yeah, but sound continues.
Christian Hellings: I'm getting a Unknown security type 3.3 error weith vnc
David Huckaby: Yes, frozen video.
Marius Buliga: video frozen now.
Leah Wrenn Berman: also here---audio OK
Parviz Khalili: Soud is Ok
Lynne Doty: video frozen, sound fine
David Huckaby: Audio fine
David Thomas: I also have frozen video, audio is fine
Matt Goeke: If the screen is coming up green, close out of quicktime and relaunch the 
application.
Hugh Sanders: My video is green, very green. Audio is fine.
Leah Wrenn Berman: video now*very* slow
Tepper Gill: Yes, mine seems to be frozen also
Derrick Head: All was fine, but now my video is frozen too.
Dennis Keeler: video is mostly frozen, a bit of ghosting.
Suzanne Riehl: My video is fine, as is audio.
Leah Wrenn Berman: and fuzzy
Laurel Cooley: I did that and it is still green, maybe it's frozen?
10:05 AM
John Boncek: ah...video just came in
Leah Wrenn Berman: well, it fixed itself now
Tepper Gill: its ok now
Parviz Khalili: Now is fine
Dennis Keeler: ok, video OK now, after restart of stream.
Leah Wrenn Berman: so I think it was the server maybe
Hugh Sanders: Now my video is very good.
Leah Wrenn Berman: without restarting
Hugh Sanders: No, I restarted and now the video is very good.
Laurel Cooley: still green
Hugh Sanders: No, it is as it should be now.
John Boncek: lost quicktime stream
Michael Siddoway: Not able to interact with "chalkboard"
Harry Mills: Fairly experienced with Maple. Just looking for more efficient/effective means 
of using it in Linear Algebra. Experience indicates that THIS professor does too much 
theory (proofs) and not enough applications.
Regina Souza: My name is Regina Souza. I have taught Linear Algebra for 3 semesters now 
(using MatLab). I would like to compare Maple with MatLab (I have no previous 
experience with Maple).
Steve Prothero: Steve Prothero -- Willamette Univ -- Salem, OR -- 42 years teaching here -- 
very little experience with Maple -- lot's with Linear Algebra
10:10 AM
David Thomas: Hi, David Thomas from Centenary College. I am a novice to Maple I have 
used it a little in multivariable calculus
David Huckaby: David Huckaby--first-year assistant prof. at Angelo State Univ. I've used 
Maple some, but I'm no expert.
Derrick Head: I'm Derrick Head from Centenary College in Shreveport. Used Maple a little 
in differential equation courses but not linear algebra
Todd Ashby: My name is W. Todd Ashby, and I teach at Charleston Southern University.
Harry Mills: Hi Steve and Regina. Since there's already a "Steve" in here, I'm going to be 
"Harry Mills". Steve, that's a nice area in Oregon.
Leah Wrenn Berman: Leah Berman---starting my 4th year at Ursinus College, outside of 
Philadelphia. I teach linear algebra regularly (once a year) and use Maple for labs, but not as 
effectively as I think I ought to be able to.
John Boncek: <-- Jack, at Troy University - Montgomery. Experienced Maple user, 
experienced Linear Algebra Teacher. I also teach Numerical Analysis.
Suzanne Riehl: I'm Suzanne Riehl. I'm a novice at Maple.
Michael Siddoway: Interested in finding new ways to present examples to my LA courses. 
Hope to be able to use the software every day in class. ALready use other software 
extensively. Wondering what MAPLE has to offer.
John Boncek: We're finally getting Maple for our branch campus, and I'd like to use it in 
both courses.
Joyce Quella: Hi, Joyce Quella from Winona State U in Minnesota. No experience with 
Maple. Teach linear algebra occasionally and am looking for good software.
Luz DeAlba has left this chat.
Dennis Keeler: Hi. I'm Dennis Keeler. 2nd year teaching at Miami U (medium size public 
u). Tried to give some Maple assignments in Calculus. I found the students had a very hard 
time with the linearity of it.
Dennis Keeler: I'm not assigned to teach Linear Algebra in the near future, but hope to get 
ideas for using Maple in Calculus classes, or perhaps Abstract Algebra. (I'm an algebraist.)
Laurel Cooley: Hi, Laurel Cooley from Brooklyn College. I've used Maple in Calculus, as 
well as Mathematica
Christian Hellings: Chris, at Gwynedd-Mercy College. Intermediate level at Maple. Looking 
for ways to use Maple in class.
Marius Buliga: Hi. I'm Marius Buliga from Univ of Pittsburgh-Bradford.Used Maple for 
Calculus before. I taught Linear Algebra twice before and used Mathematica. Thinking to 
convert the examples discussed during worksop from Maple to Mathematica.
Lynne Doty: I'm from a small math dept in a college whose most numerous majors are 
comm and pysch. I hadn't taught LA for 20 years until last fall. Now I would like to 
integrate Maple into the course primarily to illustrate the ideas in LA.
Parviz Khalili: My name is Parviz Khalili I teach at Christopher Newport University in 
Virginia. I have used Maple for years, but ours is required only in Calculus series. However 
the use of Maple in our linear algebra is optional.
Hugh Sanders: My name is Hugh Sanders. I teach at Georgia college & State University in 
Milledgeville, georgia. This is a public liberal arts university in the University System of 
Georgia, in fact the only one. I teach math and math ed.
Harry Mills: I started out with MACSYMA in the dark ages.
Frank Rooney: Maple tyro. I'm an engineer by trade, now teaching math/physics at high 
school. I'm looking to build proficiency with the program and to use the workshop as a post 
calculus semester course.
Dorothy Zeiser: My name is Dorothy Zeiser. I have been using some Maple worksheets at 
Gwynedd-Mercy College in several classes. I hope to become more familiar with Maple.
Tepper Gill: I find Matlab tends to stunt thinking in students and hope that maple will help.
Lynne Doty: Maple 10 seems to have some really useful new features. I had only used 
Maple 8 up til now.
Todd Ashby: Cont...I have used Maple (LAMP) in Linear Algebra and the Calculus 
sequence extensively. I hope to develop Maple interactive worksheets for my Linear Algebra 
class.
Harry Mills: BTW, My VNC quits when I COPY, but not when I paste. Weird.
Dennis Keeler: I liked the idea of the Maple Tutors in 9, but found some bugs in them. 
Hopefully fixed in 10.
Michael Siddoway: Frozen Screen. No AV
10:15 AM
Leah Wrenn Berman: (also BTW, the video is pretty flaky---freezes up and then unfreezes)
John Boncek: They're not 'bugs' -- they're 'features', Harry
Suzanne Riehl: I want to be convinced that using Maple helps students get the concepts. We 
don't have easy way to have a class in the lab.
Lynne Doty: Harry, I had the same problems with copy.
Hugh Sanders: Note is there an overload on the transmission, because the video is freezing?
David Huckaby: About VNC: It closes when I copy and paste. Is there a workaround?
Harry Mills: So the equation numbering is automatic (Section.Equation#)?
Hugh Sanders: The video is now OK.
Parviz Khalili: We are using Leon text book in Linear Algebra that has interesting projects 
but in Matlab rather than Maple. I am hoping that this workshop enable me to translate 
those in Maple!
Harry Mills: I'm using Lay's Linear Algebra.
Leah Wrenn Berman: me too
Lynne Doty: me too
Michael Siddoway: AV fine now
Joyce Quella: We use Lay's Linear Alg also in Winona.
John Boncek: We use Lay.
Suzanne Riehl: I use Poole; who publishes Penney's book?
10:20 AM
Harry Mills: That may suit my style better. I really kill my kids with all the vector space and 
linear independence arguments, which they dislike.
Steve Prothero: I've used lot's of different books--next time (Fall) trying Kolman
Todd Ashby: We use Lay with LAMP
Michael Siddoway: I'm using Poole this year after many years with other books
Harry Mills: Nice thing about Lay is the true-false, which forces 'em to actually READ the 
text.
Regina Souza: what is the size of your class?
John Boncek: Our students are primarily "non-traditional" -- working adults returning to 
school after many years. Their skill level is typicaly quite low, even among the mathematics 
majors. We don't have a lab for mathematics.
John Boncek: On the other hand, a 'big' linear algebra class here might have 12 students
10:25 AM
Leah Wrenn Berman: do they get to use Maple on exams?
Leah Wrenn Berman: or calculators?
Parviz Khalili: I am hoping to get a good list of Maple projects in linear algebra at the end 
of this workshop!
Harry Mills: Congrats on group-work emphasis. I like it in theory, but my experience is that 
some will work & some will sponge. This is true even in the individual work, required on 
homework.
John Boncek: Mike, Russell : What computer skills do you require of your math majors?
Mike May: John, We don't have a set of computer skill we reuire
Russell Blyth: rtsp://165.134.240.35/LA050627am2.sdp
Russell Blyth: restart QT and use this address
Leah Wrenn Berman: I didn't need to restart, BTW
Mike May: Video is back up. I find if you close the vidseo window and open URL it is a 
simple edit
Russell Blyth: Everyone OK?
John Boncek: surprisingly--- i'm fine, here in Montgomery!
Russell Blyth: JB: none
Parviz Khalili: Yes
Harry Mills: Any who have the "VNC dropped on me" problem may find it helpful to keep 
the original QT URL in their clipboard and just edit it when Russell and Mike change tapes.
Suzanne Riehl: yes
Marius Buliga: fine here.
10:30 AM
Harry Mills: The 9.5 didn't permit Equation Editor. I got really good at Control-R 
keystroke. (^-r)
Russell Blyth: Some of you will have good suggestions for improvements in our 
worksheets
John Boncek: Linear Algebra here is for math majors and for some business degree 
programs. We dont' have an Engineering school
Harry Mills: LA is for all Majors and Minors.
Harry Mills: Our students use Maple from Calculus I on. Some get a smattering in 
Transcendental Functions (Fancy name for "trig")
10:35 AM
Steve Prothero: How do I get all the garbage, buddy list, particip list, chatt log off the VNC 
screen?
Harry Mills: Students CAN grasp loops and other kinds of logical structures, but you have 
to hand it to them, rather than "test" them on these structures.
Harry Mills: All the garbage you see is what Russell has on his computer screen. You're 
seeing a live feed of his system.
Harry Mills: THIEF!
Harry Mills: Damn academics...
Harry Mills: I
Harry Mills: was teasing.
10:40 AM
Alden Monberg has declined the invitation to this chat.
Parviz Khalili: Picture freezes every once in a while!
Harry Mills: Giving students a template in Maple for a given assignment can be helpful. 
Our students here tend to already know quite a bit, but creating and managing 
sections/subsections and generally 'organizing things' is something most find
Harry Mills: challenging.
Laurel Cooley: My picture freezes most of the time
Harry Mills: Yes, Laurel. Main thing is the sound.
John Boncek: Just enough Maple ... yes
Michael Siddoway: Mostly Frozen here too. Voice fine
Tepper Gill: My picture freezes also (most of the time)
Russell Blyth: Was Just Enough Maple OK?
Harry Mills: Looking at "RandomMatrices," here. Nice to see "." instead of "DotProduct"
Dennis Keeler: yes, did Just Enough Maple. No prob.
David Thomas: I did.
Tepper Gill: Yes
Christian Hellings: Yup.
Lynne Doty: yes
Harry Mills: Yes, I did just enough...
Dorothy Zeiser: yes
Russell Blyth: That was the tutorial
Suzanne Riehl: Yes, Just enough was fine.
Marius Buliga: yes,fine
Steve Prothero: OK
Michael Siddoway: JEM done
Leah Wrenn Berman: yep
David Huckaby: yep
10:45 AM
Leah Wrenn Berman: how do the students receive the files?
Michael Siddoway: Do you use a course website extensively?
Derrick Head: Do your students submit their files electronically? Or do they just turn in a 
printout?
Parviz Khalili: are we going to get a hard copy of what we do here?
Harry Mills: One of my colleagues gives out a hard-copy MS Word worksheet, on the 
theory that it forces them to type the syntax at least once in their lives.
Leah Wrenn Berman: ugh
Harry Mills: I'm with you, Mike.
Regina Souza: voice went out
10:50 AM
Regina Souza: came back
Parviz Khalili: That will be fine.
Leah Wrenn Berman: some blips
Christian Hellings: Do we need to have Maple running? It slows my machine down a lot.
Russell Blyth: video out
Russell Blyth: New address will be
Russell Blyth: rtsp://165.134.240.35/LA050627am3.sdp
Mike May: You can run Maple or not. If it helps to do things as you watch it is helpful. If 
that causes more problems for you, do't run it at the same time.
Russell Blyth: we're on
Mike May: Video is back on
Parviz Khalili: I am on
Suzanne Riehl: I'm back. No problems
Marius Buliga: no problems here.
Harry Mills: No prob.
Michael Siddoway: Mostly "stills" but good sound
Laurel Cooley: green
John Boncek: amazing... i've connected!
David Huckaby: audio out right now
David Thomas: ok
Steve Prothero: also green, but good sound
Regina Souza: I missed which worksheet you are opening
Leah Wrenn Berman: VisualSystems.mw
Leah Wrenn Berman: audio gone
Leah Wrenn Berman: back again
10:55 AM
Harry Mills: Having trouble finding the worksheet to which you were referring. I have 
downloaded 4 worksheets in addition to the "Just Enough..."
Harry Mills: Sound Out.
Laurel Cooley: When you plot to see the solution, do you have to use solve?
Harry Mills: Sound Finally Back.
Harry Mills: May I have a URL for VisualSystems.mw?
Mike May: LC, We are doing things in a way that generalizes.
Leah Wrenn Berman: http://euler.slu.edu/PREP05/program.html
Marius Buliga: is there a way to trace graphs in Maple?
Marius Buliga: to find coordinates of intersection point?
Dennis Keeler: http://euler.slu.edu/prep05/ws/VisualSystems.mw
Mike May: When you click on a graph you get the coordinates of the point. It does not 
highlight and trace.
11:00 AM
Michael Siddoway: Do you ever throw in a nonlinear example?
Mike May: MS, I did not at this point, but that might be something to try.
Leah Wrenn Berman: At this point, you mention the * problem?
Mike May: MS, That would be worthwhile when talking about number of solutions, that 0, 
1, or infinity is really a property of linear systems.
Leah Wrenn Berman: that you need * every time you multiply?
Michael Siddoway: Also could set up some Groebner Basis work later
Mike May: The is another reason to start in R^2. THe math is trivial while they are learning 
details that will generalize.
Mike May: MS, I use Groebner Bases in Abstract Algebra for field extensions, but have not 
used them in linear algebra
11:05 AM
Leah Wrenn Berman: for #2, it's troubling that when you execute it, nothing happens...
Leah Wrenn Berman: it's hard to tell if maple didn't work or that there's no solution
Leah Wrenn Berman: sure to confuse students, though
Alden Monberg has joined this chat.
Alden Monberg has left this chat.
Michael Siddoway: I give a few "Groebner" examples to set up later work in abstract 
albegra and a computational algebra course
Regina Souza: could we add one plane at a time?
11:10 AM
Michael Siddoway: Can you simply plot the line of intersection?
Michael Siddoway: of two planes?
Regina Souza: could we plot the line of intersection of the two planes and then the third 
plane (showing the intersection of the line with the third plane)?
Mike May: To do the line of intersection, we need to plot that as a separate object. I would 
want to make sure that Maple has solved the line on intersection, and then plot the 
spacecurve.
Michael Siddoway: That's what I was after Regina. Thanks
Leah Wrenn Berman: audio is flaking out
Harry Mills: Yes, with the nice prep's you gents did already, it's more effective to have the 
worksheet open and just listen, rather than (at least for me) to use VNC to watch your 
moves after a 5-15 second lag.
Laurel Cooley: I like the black and white.
11:15 AM
Mike May: Back up
Russell Blyth: rtsp://165.134.240.35/LA050627am4.sdp
John Boncek: I agree with Harry -- that's what I'm doing here, too.
Parviz Khalili: Can we add the solution to our system and show that it sits on three plane?
Alden Monberg has joined this chat.
Leah Wrenn Berman: what would you have students turn in w.r.t. the exercises?
Lynne Doty: How did you change view of plot? Just drag on the plot?
Harry Mills: Where's the viewing angle thingie?
Mike May: top left when you click on a plot
Lynne Doty: Where's the numerical angle entry?
11:20 AM
Mike May: on the window bar
Harry Mills: Got it. Thanks.
Steve Prothero: Sound is gone
Mike May: LWB: turn in the whole worksheet electronically, with typed comments added 
after the code they execute
Harry Mills: Yes. With Maple you can give students a FAST intro to innerproduct spaces 
and the like, with the Fourier idea. Better open up the next worksheet!
Leah Wrenn Berman: and how do you grade it? Do you add comments to their electronic 
doc?
Mike May: HM: will be after lunch
Mike May: LWB: yes
Mike May: If they have missed the point I will ask them to redo it
Mike May: I have them turned in in groups, so I am not grading 25, but 7 or 8 per 
worksheet
11:25 AM
Harry Mills: Ahhhhhh! The silver lining to group-work!!!!
Mike May: 
Harry Mills: orthonormal base. yes. Maple's a great way to hit this stuff.
Mike May: exactly
John Boncek: I can imagine the rejoicing on the part of my students: We don't have to 
integrate by parts!
Mike May: draws attention away from the ugly integrals to the idea of what is being done - 
namely projection
11:30 AM
David Huckaby: I teach at 11:30 (now), so I've got to get going. Thanks for a great first 
session!
Mike May: OK - see you at 2:30 - we about to end this session
Harry Mills: 2 minutes over!? Nice. Nicer/cleaner visuals than what I did for an inner 
product space seminar.
Harry Mills: Cleaner code. Thx.
John Boncek: The Maple visuals are much nicer on the Mac than they are under Red Hat 
Linux 9.
Alden Monberg: will we see these worksheets again/
Harry Mills: Thx, guys. See you after lunch.
11:35 AM
Parviz Khalili: What is the address of your webpage?
Derrick Head: Did you say that you don't allow students to use this Fourier notebook on a 
test?
Leah Wrenn Berman: http://euler.slu.edu/PREP05/program.html
Michael Siddoway: Thanks. Fun to imagine students seeing these animations
John Boncek: Afternoon session starts at 2:30 Central?
