Hello there, 

Would you allow me to ask this (perhaps simple) question?

My goal is to express an equation as 'desired', but with no success with algsubs()/subs()/simplify(). 

Would you please show me the correct way?

Is there a means of getting Maple to detect and print the operating system which it is being run on? Searching for this topic is awkward as it returns page after page of troubleshooting guides on how to get Maple running on different operating systems.

Conventionally in Bash I would use something like: echo $(uname)

PLs, correct my code about how to find the derivative by using the loop concept in maple?

Can anyone look at this worksheet, and explain why maple seems to complicate an easily evaluated integral?

Hi, I am trying to integrate a lengthy-expression but maple does not give a result and got hanged even after waiting 1 hour and more, pls help me to handle this or is this any other way to get a result?

Hi, how to write a loop and solve the algebraic expression? is the loop and do loop are the same thing? if different then pls mention how to solve the same question by using do loop?

Suppose I have the equation C := y^2*z + yz^2 = x^2, then I want to test for which triples (x,y,z) with x,y,z in {0,1} the equation is satisfied? Is there a quick way of doing this in Maple?

I am trying to rearrange the elements of an equation by the absolute value of their coefficients. eg -3y^2 x+2x z^2+6z^2 to

2x z^2 -3y^2 +6z^2

1. How did Maple come up with this answer?

I've tried all the packages in SumTools and none of them give an answer except Hypergeometric.

2. Is there a way to trace the steps Maple is using so I can try and answer this myself?

3. Why did it sum the series when I didn't even ask - I deliberately used the inert form (no arguments though - I like what it did).

Thank you.

H1a := Sum(GAMMA(2*b - 1 + 2*n)*GAMMA(2*n - s)*(b - 1/2 + 2*n)/(GAMMA(2*b + 2*n + s)*GAMMA(2*n + 1)), n = 0 .. infinity);

H1b:=convert(H1a,Hypergeom);

The answer H1b it came up with is 

GAMMA(-s)*2^(1 + 2*b)*GAMMA(b)/(8*GAMMA(b + s)*2^(2*b));

which seems to be correct.

Hello there, 

Would please tell me how to pick up numerical vaules from answers given by 'solve()' command?

If you look at the worksheet (sorry for the error), one possible way is labeled by 'solution 1'. However, when I tried the expression in the 'attempt 1' label, I got an error. Therefore, I'm wondering if there is a way to extract the values from the answers, instead of using the 'rhs()' command.

Hello all, 

When I enter the following expression:

eqaux_2 := l__bb = L__aa0 + L__aa2 * cos(2*theta - 4/3*Pi);
 

the cos function got converted an equivalent sin function automatically and the result was displayed like this:

l__bb = L__aa0 - L__aa2*sin(2*theta + Pi/6)

Is there any way to ask Maple not to do this automatic conversion?

Hello there, 

The equations described below are third-order equations. Therefore, the number of solutions would be 3. 

However, when I tried to solve them using the 'solve' command, only two solutions came out. 

Is there any chance to find the last one?

Hello there, 

When I tried to solve an equation using the 'solve' command in Maple, I got an answer. 

However, I could not understand how Maple got to the answer. Would you tell me what steps Maple might have gone through in order to come to the answer?

Here is my worksheet:

Hi,

I was able to get Procedure 2 to work using a for - do loop. I was wondering if it is possible to speed up the calculation by using map to find the number of roots? I do not fully understand map and passing data.

tgf := proc(a, b, c, d, t, m, n)

          local X;

          X := [solve(abs(a*x + b) + abs(c*x + d) - t*x^2 + m*x - n = 0)]; 

          return nops(X);

end proc;

res := CodeTools:-Usage(map(tgf, L));
Error, (in CodeTools:-Usage) invalid input: tgf uses a 2nd argument, b, which is missing

The L Array is tripping me up, here is a partial display of the array:

Array(1..262, 1..7, [[5,2,3,9,1,1,1],[5,2,3,9,2,1,1],[5,4,3,7,1,1,1],[5,4,3,7,2,1,1],[5,5,3,6,1,1,1],[5,5,3,6,2,1,1],[5,5,4,8,1,1,2],[5,5,4,8,2,1,2], ... ,[10,10,5,10,2,2,2]], datatype = integer[4]).

I made L Array into a list of list, R. Somewhat works.

Here is the script:

Thanks for any help.

Can anyone correct me, what's wrong with it.
