Hi,

I have two separate procedures, one which solves a series of ODE's using the midpoint runge-kutta method, and one which solves using the Taylor expansion.

I am able to graph the two results (Q1 vs time) on separate graphs within the procedure, however after "end proc" I can't retrieve the figure or plot the two seperate results on the same graph to compare the values.

Is there an easy way of doing this or do I have to rewrite the procedure to include both methods?

Hi all, I'm hopeful someone can help you with this issue I am having in implementing a Maple procedure. I use to have a strong knowledge of the programme, but haven't used Maple in a couple of years and I appear to be more rusty than I recall, I keep hitting dead ends with multiple assignments, missing arguements and so forth, so I was hoping someone can help me smooth the edges!

The problem is as follows:

q1'' - f1(q1,q2) = - q1 / (q1^2 + q2^2) ^ (3/2)
