Integral of e^(-as^2)cos(Bs)ds from 0-infinity
Nevermind! I got it! That was a toughie. Thanks for the suggestions, guys from two years ago! :) One of the important tricks is to use differentiation in the frequency domain before integration by parts.- FireWalker877

F
Integral of e^(-as^2)cos(Bs)ds from 0-infinity
Hey guys, I'm bringing this one back from the dead. Would someone be so kind as to show the steps nrged has suggested. My integral is 2*integral{0,inf}( exp(-s^2)*cos(w*s)*ds ) I realize that the integral of e^(-s^2) = SQRT(pi). Would it be easier to evaluate the integral{-inf,inf}(...- FireWalker877
