Homework Help: Fourier Series of: 2sin(4000*pi*t)*sin(46000*pi*t)

  1. Oct 1, 2012 #1
    1. The problem statement, all variables and given/known data

    How can i find the magnitude spectra of 2sin(4000*pi*t)*sin(46000*pi*t)

    3. The attempt at a solution

    im not sure how to go about this question, can someone please give me some help on what i should do. I know that for a square wave i can find the fourier series coefficients of it by finding the fourier transform of one period (which is the fourier transform of standard rect function) and then use Gn = f0G1(nf0). But this question im not sure if i can do this shortcut method.
    please help, thanks.

    Given angles x and y, what is the trigonometric identity relating the sines of these angles to the sum and difference of these angles?
