Homework Help: Fourier series equation for a even square wave

  1. Jan 3, 2012 #1
    Can someone please help me with a fourier series equation for a even square wave shown below:

    F(t) = 0 when -2ms <t < -1ms
    k when -1ms <t < 1ms
    0 when 1ms <t < 2ms T=4

    Im after finding the first 10 harmonic components. To be honest struggling with this one integration is not my strong point.
