I use Maple in high school. My students deliver their homework created in Maple. Often this involves solving a number of exercises, say 7. Not all students are completely aware of how the Maple Engine works, so I tell them to put in restarts from time to time, at least when a new exercise begins. This prevents misunderstandings and loss of time which might else happen when calculations in one exercise interferes with calculations in the next exercise. One simple example...

Dear Maple Users

I know how to create 3D plots of geometrically defined objects in Maple. One can rotate the plot by plain dragging. What I would like, however, is to make the same thing happen on my website. Is it possible to export the 3D plot into some file format and embed this object on a website? They have done it on this page:

Dear Maple users

This may be a very simple question: How do I operate on the coordinates of a vector in the most streamlined way?

Lets say I have a vector <2,4,5,8,9> containing the diameters of five different circles. I want a vector V in which the coordinates are the corresponding circle areas. So the first coordinate of V should be 1/4*Pi*2^2, the next coordinate 1/4*Pi*4^2 , etc...  How is this done in the most simple way i Maple? In principle I want a method, which will work for any function ...

Dear Maple users

I read somewhere that plots with units is new in Maple 13. There is however something which is not working well:

> restart:
> T:=30 [[year]]:
> A0:=370000[[Bq]]:
> A(t):=A0*(1/2)^(t/T):
> plot(A(t), t=0..100[[year]])

I expected to see a plot of an exponential with units. A coordinate system was displayed but no function plot!! Can someone explain why? If I remove the units, the exponential appears!

I have been looking in Maple User Manual on how to create tables. It does describe how to do it manually going from cell to cell. What I am looking for is however a way to do it more automatically, like for example in Microsoft Excel, where you only need to write the formula in one cell and then copy down the formula to the rest of the cells in the actual column by dragging. I know Maple doesn't work the same way, I just want the proces automated ...
