I am not completely aware of what you mean, since I haven't followed the discussions you refer to (I am rather new to MaplePrimes). Many Danish students today are badly trained in the use of the hierarchy of the basic four operations +, -, * and /, så when they for example want to write a fraction with x in the numerator and y+z in the denominator, many will write just x/y+z and not x/(y+z) which is the right way. When using Maple notions (1D) they will make the same mistakes. Using Maple 2D notation they will discover their mistakes and write it correctly in the second try. That's why I like Maple having adapted this notation ... I think it was in version 10 or so, right? ... Also the palettes adds to the usefulness for people who are not too strong mathematically. 

On the other hand, I think many people will try to learn more and more code, when moving on in Maple. Often it is more easy and you don't need all the clicking ...

I have read somewhere that the document mode is pretty new to Maple. I have left it though and returned to Worksheet Mode, because it is easier to control and I like that one can see, which problems Maple have solved (indicated by the red arrow) and which parts of the document is plain formula writing by the user (placed in text lines). In document mode it seems to get mixed up!

I agree with you on some of what you say about point-and-click. Maple should of course be more than just point-and-click. But if it did not have this facility, Maple would leave out a big audience. Then it would not at all be an option for high school students. Here in fact the 2D math notation is very important. I don't know how the americans are doing today, but danish students are lacking a lot in understanding such basic things like the hierarchy of the four operations: +, -, / and *. If they were left with only Maple Notation (1D) they would often write mathematical expressions in a wrong way. When do they need a parentheses or not? It's sad basic school hasn't prepared them better! With the Maple 2D- notation they are able to control if the expression has been written correctly. In the same way the palettes are important in order to make the learning curve less steep. But for sure, they should try to learn some of the code themselves when they get more trained with Maple. 

I am however still puzzled why Maple hasn't got an easy way to write He-4-2. Even Mathtype has palettes for this expression, even though this program is only for typing. 

NB! Fortunately I am mostly into mathematics and physics, so I don't need this He-4-2 too much!

WOW, that is quite spectacular! I am not that familiar with this Maple programming or script syntax. Can you explain? If I remove the three none(), the numbers are moved to the right. 

I am however a bit worried that it will trouble my students in Danish highschool. I wonder if there are more ways to do it, which require less programming? I think Maple should have placed it in the Expression Palette ...

Anyway thanks a lot. I appreciate your reply. Now I know it is possible :)

Thank you so much, Georgios. I appreciate your persistence. Now the colors are fixed! I am not quite comfortable with the Maple syntax here, though. I don't follow the logic here. Now the only missing thing is to make the first finished animation stay alive!!

Thanks Georgios. I could probably automate it with a roundoff command to make it work for other constants too. There is horever a problem: When the animation of the first trajectory finishes it disappears!! I want it to stay visible, when the whole animation has stopped.

Hi again. I don't think it matters if it is version 12 or 13. I observed the same thing like you did. Both curves were red. So somehow the blue color command was overruled ... I don't know if I am on the right track in attacking the problem, or I need to take another approach in order to do what I want. I mean it really makes no sense animating the trajectory if the objects do not move with the right velocity. Then a plain still figure would be more appropriate ... I feel pretty sure Maple can do it, but maybe it needs to be programmed??

Thanks, Georgios. You actually solved another thing that I did not ask for, but still is important for me. I did not know about the view command. So now the only thing which is missing is the animations to develop in the right tempo. The trajectory with air resistance is supposed to finish at t = tslut, whereas the other one is supposed to finish at t = tmax. They do however finish at the same time. I suspect it is because of my choice of frame rate equal to 50. I can't see any way to do it properly ...

NB! Seems like you attached some images too, but they were disabled on my side!

Hi Georgios

I have now uploaded my file after making a few corrections, since I use one of my own packages. Now the worksheet should work for all people. The comments are in Danish, so you probably won't be able to read it :) The code however should be fine. And to your question as to if the plots do work independently: Yes they do, as can be seen in the worksheet.
