<P><FONT SIZE=2>Thanks Gerd, you really helped me out on the equation response.<BR>
<BR>
So I could use the &cas-command and get it to output a plot with increments of pi on the x-axis?<BR>
<BR>
I heard about the Geogebra sketching ability in Lon Capa. I am very interested in learning how to implement that for my students as well. It is hard to find information on how to do that. How do you set up a question like that?<BR>

A few things from MAXIMA we have packaged nicely in <formularesponse> and <mathresponse> (with a "switch" for R or MAXIMA). But, using the &cas-command, you can call any function within MAXIMA, <A HREF="http://maxima.sourceforge.net/documentation.html">http://maxima.sourceforge.net/documentation.html</A> . I usually try things out on the command-line first (just running MAXIMA in a terminal) before putting them into LON-CAPA.<BR>
<BR>
BTW, we also have GeoGebra support, which we currently do not "advertise" in the templates. Students can enter graph sketches, which are then graded according to rules.<BR>

That's apparently because MAXIMA wants to solve this in the complex plane:<BR>
<BR>
(%i3) solve(x^3=125,x);<BR>
5 sqrt(3) %i - 5 5 sqrt(3) %i + 5<BR>
(%o3) [x = ----------------, x = - ----------------, x = 5]<BR>
2 2<BR>
<BR>
I guess I need to work in some way to tell MAXIMA if it should stay real.<BR>
<BR>
