SUMMARY
The integral of two even functions does not automatically equal zero unless the interval of integration is symmetric about the origin. In the discussion, the integral of cos(t)*cos(2nt) from 0 to pi/2 is examined, and it is clarified that this integral does not necessarily equal zero. Additionally, the integral of cos(t)*sin(2nt) from 0 to pi/2 is also addressed, emphasizing that non-symmetric intervals prevent definitive conclusions regarding the integral's value.
