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.

Thanks a lot. That made the trick!!

Thank you so much, Scott! You are right it works well. I am however still puzzled about the logic behind this syntax: When t runs from 0 to 100[[years]], then t[[years]] should run from 0 to100 [[years]]^2 in my World. Is Maple totally consistent here?Anyway I appreciate your answer!

Right, but still it is annoying to have to strip off units to be able to make this plot, after having solved the first part of the exercise using units. Almost the same command lines need to be written twice. I simply don't understand why Maple can't handle this situation: It is clear and unambigious what units are being used for the independent variable t and the units for the dependent variabel A!

I appreciate your reply. I didn't find that functionality myself in the help menu. Big thanks!

Thanks, that solves my problem. I had not noticed the possibility of inserting a Spreadsheet from the menu, sorry! Now it works acceptable.

Some comments: I am writing a guide for my students. At the same time I am trying to find out the best working process for them. It seems like it is not possible to access data from within the Spreadsheet outside it on the command lines. I mean you cannot reference the data in the cells in the Spreadssheet outside on the command lines. So I guess when making plots from data it is better staying outside the Spreadsheet and doing everything on the command lines. The spreadsheet can on the other hand serve as a graphically better way of presenting things than what is possible on the commandlines. My applications are in Physics. Often we use The Logger Pro software from Vernier for data collection from physics experiments. Inside this program it works like a spreadsheet: Some columns are measured, others can be calculated and it is very easy producing plots from the columns. Basicly you just insert a graph and point out which data columns are going to be on each axis. I was investigating how Maple was working here. Apparently not as userfriendly, but still acceptable for some applications. On other issues Maple is far ahead when talking about doing manipulations to data and analyzing it ...

It does not work! If I put a # at the beginning of the line and press the execution button, the Spreadsheet disappears completely.

Thanks! This Spreadsheet works a little like Excel indeed. However when I accidentally execute your command line after having worked with the Spreadsheet, all data disappears. Is there a way to prevent a line of being executed when the entire worksheet button is being used?

Thanks again Georgios. I appreciate your response and I have read the thread you linked to quite thoroughly. It had some interesting points for sure, but I also got the impression that this question doesn't have an easy answer in Maple, unless that thread was outdated? To be honest I am looking for a more easy and straight-forward way. Maybe I should describe my background a little: I am a high school Teacher from Denmark with a degree in mathematics and physics, comparable to a masters degree with thesis. I have introduced Maple to our high school, and we finally purchased a school license last spring. My physics students are happy about it and very interested and enthusiastic, and so am I. I am still searching for new possibilities in Maple - obtainable for high school students - and this time the subject is: Tables. It is not a key point for us, but still it would be nice if it worked well. 

I really hope Maple will follow the road of more userfriendly interface as was initiated in version 10, I have been told. This is crucial for a broader audience, I think. In combination with their favourable license politics it could mean a step in front of Mathematica and the other alternatives like MathCad.

NB! I maintain my own Danish homepage about mathematics, it contains however one page written in English: http://www.matematiksider.dk/enigma_eng.html
