Mike May: Invitation to afternoon chat
2:25 PM
Russell Blyth: hi
David Thomas: we have banner and the adm blames all that goes wrong on 
it.
Daniel Shown has joined this chat.
John Boncek: We have a new catalog, new reigstration system, new set of 
university policies, new mathematics curriculum.....well you get the picture!
Hugh Sanders: No audio.
Luz DeAlba has joined this chat.
Joyce Quella: Have to restart my computer - would you send a new invitation 
in a couple of min? Tx
Russell Blyth: vnc is up
Joyce Quella has left this chat.
Russell Blyth: video is up pm 1
Leah Wrenn Berman: sound good here
2:30 PM
Hugh Sanders: Sound is on.
Hugh Sanders: There is feed back, echo
Hugh Sanders: Yes
Daniel Shown: is the feedback still a problem... it may have been tmeproary
Joyce Quella has joined this chat.
Derrick Head: I still hear some feedback too
Mike May: Broadcast stop for technical details
Russell Blyth: staying with pm1
Harry Mills: Hugh and Regina: Along the lines of OUR play, pay close 
attention to these mappings from 3D objects into R3.
Harry Mills: We might find something preferable to my hacking about.
2:35 PM
Mike May: Back up
Regina Souza: some ideas are too compelling for us to be able to drop them
Christian Hellings: sounds better
Daniel Shown: is audio better for all?
Harry Mills: And ideas for implementing Hugh's ideas more efficiently than 
anything I've done.
Harry Mills: Point taken, Regina, and I'll not give up entirely.
Daniel Shown: IM me directly if you have further problems.
Steve Prothero: Fine
John Boncek: audio is much improved
David Huckaby: audio good
Parviz Khalili: fine
Harry Mills: Fine.
Hugh Sanders: No echo now.
Harry Mills: My VNC defaults re-set each session, as well, FY I.
Luz DeAlba: Wow! Thanks!
2:40 PM
Marius Buliga has joined this chat.
Leah Wrenn Berman: do you happen to know if there's a way to 
force the framerate in the display command?
John Boncek: leah: I couldn't find one. But in the rotation of the square, you 
can generate more images (e..g change the pi/8 to pi/200) and that will slow 
down the motion
Todd Ashby: Wow! Nice.
Leah Wrenn Berman: I suppose you could kick the triangle into 3-
space and rotate it about the y-axis there, and force your viewpoint
2:45 PM
Regina Souza: wouldn't this be easier in 3D?
Regina Souza: neat
Marius Buliga has left this chat.
2:50 PM
Russell Blyth: we're baaaack!
Russell Blyth: pm2
Luz DeAlba: Np numbers are ugly!
John Boncek: Yes -- this worksheet could be developed in several different 
ways
2:55 PM
Harry Mills: We're looking at our worksheet, again. you may safely skip my 
part of it, Mike.
Harry Mills: Went over it and still haven't had time to implement/tailor your 
methods to our ideas in sections 3 and 5.
Harry Mills: Skip to section 6, unless Regina has something for you.
Regina Souza: something I have a question on how to
Harry Mills: Hugh's pedagogy in Section 6 is a good lead-in, but my plot 
attempts were futile therein.
Regina Souza: represent three dimensional vectors
Harry Mills: A lot of junk, there from me.
Regina Souza: Section 3 - at the end
Harry Mills: We want to plot the line parametrically.
Regina Souza: I tried to graph a grid
Regina Souza: my code is horrible
Harry Mills: Single parameter in section 6.
3:00 PM
Harry Mills: Trying to find nice renderings of the blasted thing.
Harry Mills: Messing around with functional notation. Confusing myself on 
what/how parameters are being passed. Would like to do it with a seq
Harry Mills: Then students could see where things are going over time with an 
animation.
Marius Buliga has joined this chat.
Marius Buliga: thank you.
Mike May: sorry - for some reason my invite hung
Harry Mills: I kept going to and from spacecurve idea. nice, Mike!
Harry Mills: Disgustingly simple.
Mike May: but hard to figure out
Harry Mills: You avoided "jumping down" by inserting an execution block?
Harry Mills: most kind.
Mike May: yes
Regina Souza: 
Mike May: to prevent jumping down past the next block of text to the next >
Regina Souza: end of section 3
Harry Mills: Impossible 'til you can do it. Trivial when you can. I feel like I hope 
my students will feel: Dumb for asking about something too simple. When they do 
THAT to me, I pat 'em on the back...
Mike May: yep
Harry Mills: ... and say the reason they're feeling dumb is because they did 
the work to prepare their minds for the answer.
Regina Souza: I tried to plot the sum of two vectors plus the "grid" of their 
linear combinations, taking s and t between 0 and 5
Regina Souza: right above
3:05 PM
Harry Mills has left this chat.
Harry Mills has joined this chat.
Regina Souza: is there a command to create a "double sequence"?
Harry Mills: Thanks for re-invite.
Regina Souza: s*w1+t*w2 for s and t from 0 to 5?
Regina Souza: and then a way to plot it
Frank Rooney has joined this chat.
3:10 PM
Regina Souza: that's really neat!
3:15 PM
Regina Souza: And I guess we could display side by side the same 
computations done for A^T
Regina Souza: s*w1+t&w2
Regina Souza: s and t vaying from 0 to 5, say
Christian Hellings: There are array structures, aren't there?
Christian Hellings: 2-D arrays?
Harry Mills: I did run across a function this afternoon that took pairs of vectors 
and plotted their respective coordinates as points.
Harry Mills: Yes, there are, Hellings.
Harry Mills: You might find it easier to think (and code) in the language of 
matrices, though.
Christian Hellings: I've never used arrays --- don't know if they're easy to 
work with
Harry Mills: heck, they're just matrices!
Mike May: back
Mike May: pm3
Christian Hellings: like, can you "display" and array like you can display a 
sequence
Harry Mills: No sound yet.
Luz DeAlba: That was nice with the nul and col spaces. I recall you had 
an example earlier (the first day) in which you showed vectors from one 
and the other to be perpendicular, but this is not always the case, is it?
Mike May: we have sound
Mike May: maybe restart QT again
3:20 PM
Harry Mills: Are we on pm3?
Mike May: yes
Harry Mills: Then I don't have sound. Prob'ly at this end.
Harry Mills: hellings: My answer is "yes" but Mike and Russell are much less 
likely to trip over the technicalities of "displaying" an array.
John Boncek: some kind of "contour plot"?
3:25 PM
Harry Mills has left this chat.
Christian Hellings: Thanks
Hugh Sanders: Yes
Steve Prothero: E-mail yes, chat names no
Lynne Doty: Are e-mail addresses on List Serve accurate?
Mike May: I think so
Lynne Doty: Good, that's all I need. But if others want chat names that's fine.
3:30 PM
Frank Rooney has left this chat.
Mike May: anyone having issues with the listserve?
Derrick Head: The listserv is fine with me. You can send out my chat name, 
but i rarely chat.
Mike May: I only use chat for these workshops!
Derrick Head: OK, good point
Leah Wrenn Berman: at least on the mac, I had to have a person 
listed as a buddy to be able to send files
Mike May: Are the email addresses correct for the listserve?
Leah Wrenn Berman: although I could chat without listing as a 
buddy
Mike May: Yes, I had some problems getting your files via email, but the chat 
transfer has worked great

Harry Mills: Legendre contains no 'a'
John Boncek: Midwestern accent? 
Harry Mills: )
Harry Mills: I mean )
Derrick Head: Is there an easy way to place a Maple-created animation in a 
PowerPoint file? Would you just export it as an animated gif?
Harry Mills: But your math/maple are wunnerful
Mike May: 
Derrick Head: OK Thanks David and I were both wondering about that.
John Boncek: We use Maple to generate graphics for LaTeX documents here.
3:40 PM
Harry Mills: You can also do a simple copy and then Edit-Paste Special... or 
Edit-Paste as...
Harry Mills: I'd be interested in seeing how that's done, John.
John Boncek: we export as encapsulated postscript then use the graphicx 
package
Parviz Khalili: how do you do that putting Maple int TeX
Mike May: The Maple to LaTex is a bit dicier - it depends on some Tex 
packages that come with Maple
John Boncek: true
Harry Mills: Copied and pasted your note into my notepad... as text. )
Mike May: but you need to make the packages available to your Tex
Mike May: video down
Mike May: pm4 and back
Derrick Head: Thanks for sharing both the Legendre and Chebyshev 
notebooks. They would be nice to use in an Advanced Engineering math course I 
teach
John Boncek: dhead: the Kreysig Advanced Engineering Math book has a 
Maple supplement
Derrick Head: Good thanks
3:45 PM
Dennis Keeler went offline before accepting your invitation.
3:50 PM
Parviz Khalili: Russell how long are you going to keep the Web site up? I may 
need to check some of the worksheets next week.
Luz DeAlba: Is it possible to download the video as well? I have been 
able to see again, but can I have these on my computer?
Parviz Khalili: Thanks
Marius Buliga has left this chat.
Harry Mills: listserv particulars?
Harry Mills: Don't you have to subscribe, first? Been years since I used 
listserv's
David Thomas: is the address on the website?
Harry Mills: Haven't received any e-mail, yet.
John Boncek: Yes -- I'd like to hear from folks on the listserv. We are a two-
professor deployment at a branch campus, so we sometimes feel isolated from 
the world.
Harry Mills: Heh. Spammers!
Harry Mills: Will speak with administrators.
Harry Mills: Protocol in the old days was something like "Subscribe" as subject 
line or "Subscribe" as mesg body (without signature)
Steve Prothero: Just looked at my olde emails -- all came from one or the 
other of you, from slu, not from a listserv
3:55 PM
Parviz Khalili: What is the address of the other workshops?
Harry Mills: Bread upon the waters...
Steve Prothero: But I got the emails--no spam problems--just standard return 
addresses
Parviz Khalili: Thanks
Harry Mills: Yes.PREP-MAPLE-2005@ENTERPRISE.MAA.ORG
Mike May: yes
Harry Mills: Thanks, gents.
Derrick Head: Yes, Mark S. was hoping to join us, but he had other 
commitments this week.
Parviz Khalili: Appreciate your work. Hope to stay in touch with you guys 
during the year. Nice job
David Huckaby: Yes, thank you very much for a great workshop!
Todd Ashby: Gentlemen, enjoyed it. Thanks!
4:00 PM
David Thomas: Thanks I learned a bunch
Derrick Head: Thanks so much, guys!
Steve Prothero: Is there an evaluation?
John Boncek: This was excellent. Yes, thanks to everyone!
Christian Hellings: This was very enjoyable and educational. Thanks.
Dorothy Zeiser: Thanks for a great week!
Luz DeAlba: Thanks to all!
Parviz Khalili: It took the fear of maple out of me
Regina Souza: thank you very much!
John Boncek: 
Hugh Sanders: I really enjoyed this. It was very valuable.
Parviz Khalili: I guess
John Boncek: enough to do some real damage. 
Parviz Khalili: The programming is not trivial
John Boncek: This sort of class gives us ammunition -- why we need more 
resources! (Including network bandwidth!)
Steve Prothero: Thanks for a great time
Mike May: bye
Mike May: video off
Hugh Sanders: Thanks again.
