Homework Help: Integral of even functions

  1. Oct 20, 2005 #1
    Would the integral of two even functions be 0 or not? I have an integral cos(t)*cos(2nt)that goes from 0 to pi/2 and was wondering if that would automatically be 0 or would the integral of cos(t)*sin(2nt) from 0 to pi/2 be 0? Thanks!

    If the interval of integration is not SYMETRIC (ex: (-L,L), you cannot conclude.
