How can we learn all the trigonometric formulae with Euler's formula?
This is all really fascinating. Is there anything else I should know about using Euler's formula to learn trigonometric identities?
One interesting fact is that Euler's formula can be used to prove De Moivre's theorem, which relates to the powers of complex numbers in polar form. But that's a topic for another day. Do you have any other questions on this topic?
