Hi,

Assume having to solve an ode with dsolve and plotting with odeplot. Further, markings at specific parameter values of the solution should be plotted, i.e. if p is the solution of the ode, the points p(t1), p(t2), ... should be plotted. Since the ode is complicated and computation takes a lot of time, is there a way to extract the values p(t1), ... from the odeplot result directly without invoking calls like subs(p(0.5),b(s)) again?

I want to describe the problem differently: I start with a rational function (polynomial/polynomial) B in two indeterminates x,y which is already quite lengthy (about 80 lines on my worksheet) and want to perform several (algebraic...

Hello,

I want to build a paper model of an immersion of real projective plane made out of paper strips. I want to use maple to plot the curves which represent the paper strips. I have written a code shown below which computes the curve for one of the strips. In this code, alpha is set to Pi/2 and the computation goes through. However the computation should be performed for various alpha. But if I set alpha=0, then f (see code below) is not computable, if I set alpha=Pi/4,...
