Can someone tell me how to calculate the Christoffel symbols in spherical coordinates in Euclidean three dimensional space?

Thank you very much in advance!

Hello 

I am working on my vector file and have another question:

1. How do I display any vectors in a matrix notation next to each other or above each other (like: [1;2;3]) 

Find attached the file:question_vector_.mw

I really appreciate any help you can provide.

At the end of this link - (2.14) and (2.15) - the problem and the solution have the same maple code, so I don't understand how to solve the problem.

Is it possible to have a variable in a filename ?

as an example if I save a file by

save M, "Result(Variable).txt";

So If Variable is e.g. set to

Variable:=10;
then the filename saved should be
Result(10).txt

It is not that this a terribly difficult to work out, but I feel I am probably missing something. I need to check if a 3D point lies on a 3D line. What is a good approach here. I started of with the idea all alpha's are equal. but there are exceptions. See P3 and P4

I don't know what that line above the question is. Thanks in Advance.

I'm trying to get my problems in standard form  a + bi . Questions 19 - 22 are wrong.

As a Maple beginner, I am now interested in symbolic calculations in Maple. As before, I set a problem from a subject area that interests me in order to learn from professional answers.

Determine all regular square (n;n) matrices (determinant not equal to zero) that are commutable with every regular (n;n) matrix with respect to matrix multiplication.

(I know the solution from long ago.)

Example code

printlevel :=1     

for indx1 from 1 by 1 to  3  do  

f[indx1] :=indx1;  

 end do;

This prints
f₁:=1
f₂:=2
f₃:=3

How do I use the "save" command to save exactly the loop's results above to a file so that I can read the file later and execute it in another  maple worksheet.

The maple manual https://www.maplesoft.com/support/help/Maple/view.aspx? 

for "save"   contains no examples, and definately not how to save results of a loop using the save command. e.g. how do you append  with a file using the "save" command ?

Note: I dont need any help with reading the results, from the saved file, my question is only about writing the results with "save" command. The "save" command gives me the best results for reading files back into a speadsheet, and text file save routines just gives me ascii garbage and not the exact results in executable maple format as "save" does, saving exacltly what you see on screen. Therefore text save routines are useless to me.

I have a file TEST.m. How can I make it so that every time I start Maple, all the subprograms in the TEST.m file will run first? Then I just need to type the function with(TEST): sumpro(2,3,4) to get the result 9. I copied the TEST.m file into Maple's lib directory, but it doesn't run after starting Maple.

I just need to type sumvip(2, 3, 4) to get the result, but Maple doesn't understand it.

Please help.

Solve the general cubic. Apply values and simplify. 

Could someone show how Maple simplifies to the value of X=3? I tried doing it manually and I could not figure it out. 

Also is there a Help assistant to see the setps?

In the decimal system, we are looking for all natural numbers with at most six digits that only swap the order of the digits when multiplied by 2, 3, ..., 6.
