Question
I’m so sorry, can someone please explain to me what these c0,c1,c2, etc are in the response I just received from you guys? I’ll send my original question and the response. I have just never seen that before! I super appreciate you guys! I was just getting stuck on using Euler’s identity to find the quadruple angles for sine and cos. Thanks!
