I'd like to evaluate a bunch of integrals where the outcome of the

integration will contain factors like Exp[I 2 Pi q], and tell Mathematica that

the symbol q is an integer, i.e.

Integrate[ --integrand --, {--limits--}, Assumption->{q is an integer}]

How can I do this? The symbol q appears in the limits, not the

integrand, if that matters.

you are looking for the Element command and the Integers domain:

Element[q,Integers]

You can specify that it is an integer by

Assumption->{Element[q, Integers]}

Assumption->{Element[q, Integers]}

Still, this does not help, if I want to prove that the Legendre

polynomials are orthogonal.
