This is how math proofs should be explained: clear and logical steps. Small consideration, just personal, I really appreciate how you did all this without saying a word. Perhaps math really is a language

I loved learning about maclaurin series and exponential form of complex numbers, and I specially enjoyed learning about this proof! You presented it very clearly :)

Clear and concise. Maybe some inspirational, classical music next time?
