Shit I just realized why EEs use cosine for waves: because a cosine wave with a frequency of 0 is just a DC signal. A sine wave with a frequency of 0 is just 0

I guess a sine wave with a frequency of 0 is a DC signal in the complex plane but that makes all the math break so we avoid it

Why will nobody sell me the forbidden 12j volt power supply
