dotpro := (psi,phi,L)->int(evalc(conjugate(psi)*phi),x=-L..L);

dotpro(exp(I/hbar*p*x)/sqrt(2*L), exp(I/hbar*q*x)/sqrt(2*L),L);

limit(,L=infinity);

restart;

> assume(L>0);

dotpro := (psi,phi,L)->int(evalc(conjugate(psi)*phi),x=-L..L);

dotpro(exp(I/hbar*p*x)/sqrt(2*L), exp(I/hbar*q*x)/sqrt(2*L),L);

> combine();

limit(,L=infinity);

# The result is neither the limiting value, nor the function calling sequence Maple Equation
