My integral calculus is a little rusty. There was an exercise in the first lecture series where we calculated the average power by integrating the COS waveform over one cycle. I'm sorry I don't have the problem in front of me. Can anyone show me how this is done? I'm a little confused.
For example: how do you integrate (cos(2*pi*60t))^2 over one cycle?
I fill in more detail when I get home tonight if needed.
