@mmcdara  and  Carl Love 24237

Thank you very much both for your help. Problem solved.

@Christopher2222 

Thank you for taking the time to look that up. For an unknown reason, Maple refused to cooperate. But today, I tried it again and it works perfectly. So it was clearly again a question of windows interaction with Maple. I should have taken the time to restart windows and try again. Sorry for the trouble.

@ecterrab The d_ was the thing I was not sure.

Thank you very much Steve and Edgardo for all of this. One thing I am doing is to prove this two relations that I saw on the Web:

Of course, the notation at the right of the equations won't appear like that in Maple.  Thank you in advance.

Thank you both dharr 1781 and acer 22068 .

Acer, as always, the solution that I needed. The procedure Lg is the way I will go. I could not find a way to introduce the constraint i<>j. The if was the solution. Thanks again.

Mario

@dharr 

Thank you for that command. 

You did not use the parameter "form=Lagrange". I explore this and it seems to be it. But you cannot specify the order N+1. It must be link with the number of points. And that command calculates li and u bar at the same time. Very interesting! I was able to do a good example in a document that I have included here:A_little_example.mw

By the way, I am still interested to do this calculation:

because I want to learn how to manage a case with i<>j

@rlopez 

You are right. Here the new version. I am so sorry for those who downloaded the wrong version two times. I had to put a «c» after p_[mu] to obtain the right (15). Now I can square both sides and I had to correct manually equations (A). I should have mentioned that the equations A through E were manually written in the document because that's the place I have a problem.

@rlopez 

I did have an error so I am attaching the revised document.  I had to add one element, so now we have A, B, C, D, and E. So now it is correct. So I have the same question, how to obtain A, B, C, D, and E with the clickable functionality. I tried working with the Equation Manipulator but with no success.

Thank you.

@tomleslie 

by saying to me: Or is that a bit difficult for you to understand?

Your last response starting with « I think that ... » and finishing with the plot would have been the exact response I would have liked to receive.

Here is not the place to talk about the way I teach. But if you are interested, it would be my pleasure to exchange an email with you.

@tomleslie 

Well, I have attached a Maple document and an image inside. All the solutions you gave are wrong from the point of view of a physicist.  If a student was to give me that kind of graph, I would have to give him a 0.  Look at the image and you will see what region is the real solution. And the only simple thing I ask is how to plot the right region.  In the document, the first graph is half of the solution.  I want a command that will show how to have the right region fill with color. And never will I give points to someone that starts the masse M and m at -10.  Maybe I should have stated that I was a physicist.

@tomleslie 

The mass «m» and «M» cannot be negative.  The plot is wrong of course.  Moreover, we don't see the relation M>2*m

@ecterrab By the way, I do have a problem installing it under windows.  I did the command and I receive this message:

`The "Physics Updates" version "865" is installed but is not active. The active version of Physics is within the library C:\\Program Files\\Maple 2020\\lib\\maple.mla, created 2020, March 4, 20:36 hours`

Then I did Physics:-Version(latest) and after some times, a window opens stating that;

"Connection to the kernel has been lost"

I don't have any firewall installed.

Any ideas?

I am using Maple 2020.1 id 1482634.  What command should I do to find the version of my physics package?

Thank you in advance.

Mario

@acer 

As you will see in the attached document, I don't get the true numbers on the vertical axis but the unit is good. The horizontal axis is OK.  Then equation (4) print OK but why (6) is not?  Do you see what I am doing wrong?  I am using Maple 2020.1

Thank you in advance for your help.
