Euler's number trick - Jesse Hyttinen

Hi and welcome to the Matladpi blog! In this post I will concentrate on Euler's number e, and will show a trick you can utilize to solve some types of equations.

Euler's number has a property that can be used to solve these equations, namely

e^(ix) = cos(x) + isin(x)

, where i is the imaginary number with a property i^2 = -1.

Here is the picture showcasing this trick:

Notice that after we have checked the solutions for a whole cycle, we don't check further solutions as they would only repeat the values already obtained. Njäf! said.
