Triangular and sawtooth waveforms. I solved for the coeffiecients for the square wave, and was wondering if you do the same for triangular and sawtooth. I keep getting large/messy integrals that do not seem to simplify. The thing that is messing me up is that the waveform is linear with a slope, as opposed to just 1/-1. Which would require us to solve by integration by parts. Are there any worked up examples regarding these. I would like to see the answer I am supposed to get and try to work through it.
