Hello everyone,

I'm currently exploring the properties of a sum in Maple, and I was wondering how to obtain the values of the following sum:

sum 1/(i*j*k*) such that 1<=i+j+k<= n 

I'm interested in the values of this sum for a given n. How can I express this efficiently in Maple?

Thanks in advance for your help!

Hello everyone
I have this equation (3+2*x+3*x²)ⁿ=Sum(b_i*xⁱ,i=0..2*n)
I want to determine the b_i values for any n in N how to do that ?

I thank you in advance.

Hello everyone.

I want to  choose the  numbers among the list A which are for example congruent to 1 mod 3

A = {3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101}
