Dear Maple users

I know how to plot surfaces in 3D. However now I have a special task: I want to plot a piece of a solid region in 3D, more precisely a transverse or logitudinal wave. I wonder if there is an easy way to do this in Maple? Any hint will be appreciated!

Regards,

Erik

Dear Maple users

This may be an easy task, but I cannot seem to find out how to do it: How do I get the solutions of an equation on a list form? Let's say the output of the solve command has the reference number (1), then I tried using the convert command and a label to refer to the Maple output, but it didn't work:

convert((1),list)

I hope someone can help me do it.

I like to use animations in Maple for different educational purposes. The other day I tried making an animation simulating a simplified Epicycle, which is a small circle with its centre running on a larger circle. The smaller one has a ball running on it with a constant velocity. I used the following code:

> with(plots);
> with(plottools);
> omega := 1; k := 5; R := 5; r := 2;
>
> plot1 := plot([R*cos(omega*t), R*sin(omega*t), t = 0 .. 2*Pi]);

I have been using random numbers in other applications than Maple. Usually there is a function, which will give a pseudo random real number between 0 and 1. When I looked for it in Maple I got quite confused, because there are a lot of different options here - obviously because Maple can deliver random numbers/objects in many ways, even following a certain distrubution. I found out it doesn't work by just using rand(), since it is always starting with the same value. Then I found the command randomize(...

Dear Maple Users

I am pretty new to programming in Maple, so maybe this is not a very difficult question to answer. I want to write some code, which generates a table to be displayed. In every cell I want some content, which is generated by some code as well. How can it be done, and if there are several ways, which one is the best?
