It all makes sense now

Quite the topic on SMD, funny how the video shows that the harmonics are summing to produce the square wave but never said the infinite series needed to produce a perfect square. Whats also not said is the scaling, this is important part of Fourier series. In the time domain the representation of a square is decreasing vectors, signified by the scaling of the harmonics. Wait till ya gotta do the actual integrals solving for ck and Eulers formula. Hated that shit.
