I have seen on: https://www.allaboutcircuits.com/textbook/alternating-current/chpt-7/other-waveshapes/
right under the picture of the half wave rectified fourier analysis that it contains even numbered harmonics. They also tell you that it is actually cosine waves, so are all even numbered harmonics cosine waves? If so, how can doubling the frequency cause the wave to be 90 degrees out of phase (as a cosine wave would).
