With the polar form of complex numbers established, the matter of Euler’s Identity is merely a special case of a+bi for a = -1 and b = 0. Consequently for the polar form re iφ , this makes r ...

For example, 11 is a prime number since 11 dots form only rectangular arrays of sizes 1 by 11 and 11 by 1. Conversely, 12 is not prime since you can use 12 dots to make an array of 3 by 4 dots ...
