I don't see what the issue is with the code below:
phinS=e^(i*n*pi*x/a);
phim=e^(-i*m*pi*x/a);
a=var('a');
assume(a > 0);
n=1;
m=1;
integrate(phinS*phim,x,-a,a)
I get this undecipherable error:
Traceback (most recent call last): integrate(phinS*phim,x,-a,a)
File "", line 1, in <module>

Any suggestions?
Thanks,
