Complex exponential form -- fixed incomplete sentence
The 'complex exponential form' article had an incomplete sentence before the expression for taking the real part, so the significance of doing so was never explained. This is now fixed. Also added further language explaining why one would take the real part (viz, it corresponds to the wave one would physically observe rather than the mathematical too to represent it). 152.3.43.53 (talk) 16:11, 7 December 2022 (UTC)
