                          A := {4, 5, 6, -9}

E:={a,a,-2,4,-6};
                         E := {-2, 4, -6, a}

how does maple treat sets , and  what is the diffrence between sets and lists ?

create the sequence of exp (((aπ) / b)) for a varying from 1 to 15 and b varying from 1 to 10.

Display integers between -10 and 20. Put integers between -10 and 20 in a list.

Display the odd integers between 115 and 231, then put them in a list

Construct a procedure that takes as argument a sorted list, an element n and returns the place of n if it belongs to the list, the sequence NULL otherwise.

i want to calculate the eigenvalues and eigenvectors of two matrices ,i get these results, can anyone explain to me the meaning ?

A:=linalg[matrix](3,3,[-1,2,0,4,-2,3,0,1,-3]);
> B:=linalg[matrix](3,3,[2,0,1,4,-1,1,2,0,-5]);

> eigenvalues(A);

what is the diffrence between these 2 commands ? has(H,integer), type(H,integer);

how to obtain the sequence of sin(((Kπ)/4)), where the integer K  is varying from 1 to 8, and then to delete the zeros.

i'm triying to solve this sytem ,

solve({x^2+y^2=3,x^2+2*y^2=3},{x,y});
{y = 0, x = RootOf(_Z^2-3)}
what is the meaning of RootOf

maple gives me this, can anyone explain to me,the signification of the solutions ?

Write a command maple to count each two elements distincts of a list L ?

to get the list where all the elements of a list L equal to its largest element are replaced by 0 ?

Can there be approximate ways of calculating the derivative? Maybe I should count on some formula? Or can not it be calculated in any way at all?

Where is the mistake?
 

0^0 gives error ,0^0 is undefined, why  maple gives this result?
