Including Graphs in Questions
If you choose "Use
HTML formatting for the question text" when constructing a
question it's possible to have Maple T.A. insert a graph
into the text. The text show
in this font can
be pasted into the question window. It's important to note
that the contents beginning <script> and ending with
</script> must be contained on a single line. If
broken across more than one line this call to Maple T.A.
will fail (and no graph will be shown).
Including a surface plot
For example, here is some
content that can be pasted into the question Text Area to
view a surface in three dimensions. (Note that I've only
shown the plot after each example in this section: the
question text is, of course, also included on the page. )
What is the maximum value of the function plotted
here?
<script>drawMaplePlot("plot3d((x^2+y^2)*exp(1-x^2-y^2),x=-2..2,y=-2..2,axes=framed,scaling=constrained,grid=[50,50])");</script>
Plotting Points:
A basic plot connecting a sequence
of points it's a little awkward, but certainly possible.
Is the relationship linear?
<script>drawMaplePlot("plot([[0,0],[0.5,0.5],[1,2],[1.5,2.5],[2,1],[2.5,7],[3,5]])");</script>
Discontinuous functions:
Complicating things a
little: you can plot discontinuous functions by defining
them within the drawMaplePlot routine:
Is the plotted function continuous?
<script>drawMaplePlot("g:=proc(x) if x>2
then x^2-3*x+2;elif x>0 and x<=2 then 1-x^3; else
x^3; end if; end proc:
plot(g,-1..3,discont=true)");</script>
