[LON-CAPA-users] Having an equation or a range as a response

Thanks Gerd, you really helped me out on the equation response.
So I could use the &cas-command and get it to output a plot with increments of pi on the x-axis?
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?

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, http://maxima.sourceforge.net/documentation.html . I usually try things out on the command-line first (just running MAXIMA in a terminal) before putting them into LON-CAPA.
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.

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