VNC & AIM both good here
I am not getting VNC.
qt up ok, waiting for vnc address
Daniel Shown has joined this chat.
hello.
Costel Ionita has joined this chat.
I need VNC address and QT address.
Jen Roche has joined this chat.
QT & VNC OK here
Susan Wildstrom has joined this chat.
With old VNC address I failed to get connection
vnc addr 165.134.13.229:5901 Ok?
yes
David Burton has joined this chat.
vnc
the old VNC address hould now be working.
I got the VNC connection
I just started it.
vnc is working ok here
as many as possible please use the new vnc
Everyone should try the new vnc address
9:55 AM
yes
unless you can't
I need QT URL
old VNC is up, but only use it if you can't get the new VNC address to work
If you can't do the new vnc address, please let us know
Sarah Raynor has joined this chat.
I'm on VNC on new address - looks good.
Meg Onoda has joined this chat.
!
?
Susan: let's try this AIM thing a bit  I like what you wrote so far... but are we going to limit the worksheet to curvature in 2D?
QT URL please
John Willemain has left this chat.
i have suddenly been getting underlines in my im's and don't know why.
John Willemain has joined this chat.
Not necessarily, but I figure we have to start somewhere. The problem with chatting here is that we are sort of in with everyone else.
someone can tell you how to control text styles in AIM
rtsp://165.134.240.35/mvc070627am.sdp QT address
Thanks. I got QT
ah yes. I'll send email instead 
I am doing a rotation with a live graph, tell me how it looks.
decent
looks okay here
very nice
10:00 AM
Looks good
ok here too
imok
there is a u button just above where you type
Would you send email with the link to all that other stuff you showed at Mike's website later today please
it is a toggle, just click it and it should go off
got it, thanks. just like a word processor
I've sent Linda a note
She hasn't responded
np
no problem
got that one 

10:05 AM
I find myself wishing for a way to know when Maple is processing - so I know how long to wait. Is there a "processing" thermometer that I'm not seeing?
along the bottom you may see an indicator
it says "Ready" lower left when it is done
invite rich wilders to chat, please?
done
a h- the FAR left - didn't look that far. thnks.
The timer also ticks away during computations (lower right side of screen)
yep
Please invite Jan Hlavacek.
Rich is not responding
Jan is invited
by two of us
Rich isn't getting your invite
sometimes it says ready before it actually is
just so you know
i'll try to see if Daniel can invite the missing people
Linda Gao also needs an invite
Jan Hlavacek has joined this chat.
I am in, I think (hope)
10:10 AM
Jan Hlavacek has left this chat.
can we embed comments in code?
by using # I think
VNC frozen?
Jan Hlavacek has joined this chat.
Ok, thanks everybody!
I tried # at the end of a line and all still worked
yes, my vnc is not updating
Rob, restart VNC...
David Schmitz has joined this chat.
new, i think
which is the new VNC?
New, I believe
New and not updating right now--can't see your comment you just typed
i didn't change from yesterday aftenroon
new one froze, but kill/restart fixed it.
I restarted
fine, Rob?
yep, it's ok after restart
Yep
good now
165.134.13.229 is the new VNC
what is the new one? or, do something so I can tell if it is working
thanks
Linda Gao has joined this chat.
Still frozen. What do you suggest?
restart vnc
right, restart the program
hi Linda
hi
Have the new chat invites been sent yet?
are you connected?
which VNC is still frozen, old or new?
yes
all works well here
that is the vnc I'm using
rich wilders
quoting rich: "no I have not"
okay
the invite window may be hiding behind other windows
10:15 AM
try minimizing some windows, and bringing your chat client to the foreground
if your VNC is freezing, please type the IP address you are attempting to connect to
Ok for VNC
getting a complaint that RichWilders is busy. Does anyone know what he's done?
he may have accidentally set himself as unavailable/away?
VNC Address: 165.134.13.229:5901 froze earlier but when I quit and restarted, I was able to follow along
he may have set his status to "busy" or "away"
Richard Wilders has joined this chat.
yay
Thanks -
ok, if you continue to have problems, please let us know
10:20 AM
just a comment--students can be confused because the gradplot command is not too scale, the vectors are much shorter than they should be
Maple does that so it is not just a sea of black
 yeah, I try to have NO NUMBER appear twice in any example - kind of an interesting challenge sometimes...
10:25 AM
qt just died
what is new vnc address?
try restarting, feed should be live
i have audio but no video
vnc: 165.134.13.229:5901
165.134.13.229:5901
now it works. Thanks
we have video
I get an error message when I run the worksheet you sent
ok, audio's back but frozen video... i can live with that ...
Rich?
what error message are you receiving?
Yes - it says unable to evlaute function to numeric values in region
the function has not been defined - go back and execute that line
10:30 AM
got it - I assumed it was all one big line of code as before
ok
lost audio...
ok, back again... maybe it'll last ...
all ok here
You have to love technology
which applet for multivar?
will you put the URL for this on "our" site?
sure

i've lost qt
restart qt
restarted - it's ok now

10:45 AM
what does the ` mean?
mine is changing colors
even with the set color to green
name not value, like address not instance in c++
10:50 AM
say again: the hardest part is ???
which text?
ah yes... that is usually the biggest problem...
That's because kids are in a hurry to get to calculus at the expense of learning algebra!
i second that thought...
favorite topic in our lounge
10:55 AM
ours mostly want a grade with minimum effort
after all, they're paying a lot of $$$...
algebra:mathematics::grammar:English
They don't talk so good either!
my kids don't have the $$ excuse... I think I really just haven't had enough practice. I'm considering an "Algebra every thursday" problem set next year...
Is there a way of evaluating the RootOf without manually typing it in?
It's the way the curriculum changed after about 1989 Iwere you teaching then?)
great idea: mine have a hard time factoring the difference of two squares
Below you typed it in to evaluate f
so you can't do all at once
11:00 AM
You can send a kid to college, but you cannot make them think
So would yo ulet kids use Maple like this on a test????
I am not yet comfortable enough with Maple to contemplate that. After a while I would make up Maple-only questions
Are the kids allowed to bring in "code" for the tests?
I agree with Mike about that.
my kids don't make good choices - they'll waste a ton of time trying to do it with maple...
ah - good idea. so a "with tech" and "without tech" part...
11:05 AM
TI89
I would prefer to test over concepts and not over facility with technology
My word is "judicious" use of the technology.
I routinely print things from maple and ask students to intepret them
you liked the 0.92 average???
Q3 on with or without TI part, of AB or BC?
good choice 'wild' I like your handle and that of Algebrachick, very heartwarming
3 is with

I liked the type of question, but it tested too many concepts simultaneously
My last name is Wildstrom so kids call me stuff like wildlady but that was already taken.
I don't mean time, I mean that to earn any points they had to put at least 3 different, major concepts together
but this is a conversation for another time 
yep
In 3d plots, contrast grid=[5,5] with grid=[20,20]
11:10 AM
hey - did you change the worksheet? I'm getting different graphs...
advancedplotting
ah - i grabbed them last night so i could come in late today - will regrab later
np
11:15 AM
yes, this is great. will get my less techy kids involved fast
11:20 AM
Why are the function and the tangent line changing colors on my machine when I run that animation?
It helps in the framer routine to force the colors to the graph and tangent line - otherwise they flip
put them in [ ] and then add color = [red, green] in the plot command of framer
Thanks, Darth
11:25 AM
With the force as my ally, colors are trivial...
just black
Will it output the numerical result as well?
the MVT even gave a good error msg when MVT didn't apply. very nice
change the output from plot
some of these give the numerical values
the approximateint one is my favorite, the students love seeing the little prisms filling up the graph
11:30 AM
What's the interrupt key? I put in stupidly big value and it's crunching too long...
the big hand with the stop sign along the top bar
got it. thx.
