Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: caprilo (caprilo) Assigned to: Nobody/Anonymous (nobody) Summary: incorrect integration of %e^((x^2*a^2))*cos(b*x) Initial Comment: The result of integrate(exp((x^2*a^2))*cos(b*x),x,inf,inf); is 0 no matter if you answer that a is or is not 0. The result should be sqrt(%pi)*exp(b^2/(4*a^2)) Strangely, the result of integrate(exp((x^2*a^2))*cos(b*x),x,0,inf); is "und" (the integrand is even), and the result of integrate(exp((x^2))*cos(b*x),x,inf,inf); is correct.
