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 am experiencing a strange problem with my clipboard. I am using Ducument Mode and when I am trying to copy part of my document using Ctrl+C and place it in the same document using Ctrl+V, then sometimes things are not being copied properly as can be seen on my image below. It is as though the clipboard doesn't pick up the fomatting. When I restart my computer things works fine until a certain point when it stops working. I hope someone can...

Dear Maple users

The formula f = c/λ is expressing the frequency in terms of the velocity of light  c and the wavelength λ. Lets say given not just one wavelength, but a whole list af wavelengths. The values have units attached. I wonder if there is an elegant way to have Maple calculate the all the frequencies, eventually delivering them in a new list?

I want the units of the output reduced to SI-units,...

Dear Maple users

 

My question is pretty basic: How do I put a "hat" on top of a variable, for example putting ^ on top of say x? It is useful for me even though the solution might not have any computational meaning, since I only need to write it as "written math" in 2D-notation. The Accents palette does have several symbols, but not the one I am looking for. In certain areas of mathematics A hat or the like does have a...

Dear Maple Users

I have encountered some strange behavior when trying to copy a vector:

In the first section I define a vector a and try to copy that vector and assign it to an variable b. Then changing the first coordinate in the copied vector b actually change the original vector as...

Dear Maple users

I have been looking for the list of fonts used by Maple, but couldn't find it. Can someone refer me to it? I am installing lots of programs on a new computer, and since some of them are graphics programs, I get a load of fonts thrown in my Windows Font folder. Therefore it is my intention to remove a lot of the unnecessary fonts. But I don't want to remove the ones used my Maple, so I will...
