I have a degree in Mathematics and Physics from the Danish University Aarhus, comparable to a masters degree with thesis - majoring in Mathematics. In 1991-92 I was a visting scholar at UCLA, Los Angeles, following graduate courses in Applied Mathematics. Since 1992 I have been a teacher in a high school (gymnasium) in Denmark. Special interests: Applied mathematics, graphics and popularizing Mathematics.

Dear Maple Users

I was looking forward to having the Units package improved in Maple 15. Units are indeed converted to SI Units when direct calculations are made. It is a disappointment though that this conversion doesn't occur when solving equations as the example below show:

 

Unfortunately Maplesoft mix up their announcements for news in version 15 of Maple with...

Dear Maple users

I know how to create an animation of a sine curve moving over time (t) on an x-axis to simulate a moving wave. In the help menu under the topic plots,animation it is explained how to animate a ball moving along some curve. How do I combine those two animations into one? The ball is moving along a curve completely different from the sine curve!

Dear Maple users

Often I use Maple for solving problems in Physics. Maple does indeed a nice job when calculating expressions containing units. However when I want to plot functions containing units it sometimes work and sometimes not. Look at the following example: 

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:
