I would like to take the sin of a procedure, but it keeps giving me an error. Is it possible at all, or should I rewrite it into a matrix?

like this: sin(proc(x)...end proc)

Hi all,

This might be more a mathematical problem than a Maple problem, but still maybe somebody could help me out.

I am trying to solve the differential equation of an Euler-Bernoulli beam with an distributed load (q1) and a varying axial force (N(x)). The following equation applies:



I am trying to solve a three-point BVP, but Maple returns the error:

Error, (in dsolve/numeric/process_input) boundary conditions specified at too many points: {0, 100, 150}, can only solve two-point boundary value problems

Is Maple just not able to solve 3-point BVP's or is there another way?

Hi all,

I have a problem with dsolve. I have a 2-d (thin shell) theory which I am solving with Maple. For a Simply supported beam, there is no problem, it solution is more or less what you would expect. When I make 1 side as a clamped edge (x=0), there is a problem. The total result is 'ok', but it gives a peak in the 2nd derivative of Urn at x=0. This peak results in unrealistic stresses, etc.

I don't exactly know what the problem is. It seems there is a problem...

I have a 3dplot of a certain procedure with the color specified by another procedure. 

The standard color range, from red to purple, does not look very good in my application. Is there a way to change the color range to for instance: light green to dark red?
