Dear Maple users

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?

Dear Maple users

I am working on importing data from an Excel-file "Data.xlsx" into Maple. This is done using the following commands:

> restart;
> with(ExcelTools);
> X := Import("Data.xlsx", 1, "A3:A63");

One strange behavior is the fact that I receive an error message: Error, (in ExcelTools:-Import) Could not open the file.

When I close the Maple file and open it again and reexecute, the error disappers and everything works....

Dear Maple Users

In Maple 16 I read in the menu Help > What's New that it is now possible to have 3D plots exported as vector graphics, when using EPS export. I tried it, but could not open the resulting EPS file. I used my CorelDRAW 15 Suite ... Can someone tell me how I get access to the exported vector graphics?

If I cannot get it into CorelDRAW, it is not for much use. Maybe an intermediate process?

Regards,

Erik
