What does Euler's formula do?
What is Euler's Formula Used For? Euler's formula in geometry is used for determining the relation between the faces and vertices of polyhedra. And in trigonometry, Euler's formula is used for tracing the unit circle.
What is the relationship between e and sin and cos?
Euler's formula is eⁱˣ=cos(x)+i⋅sin(x), and Euler's Identity is e^(iπ)+1=0. See how these are obtained from the Maclaurin series of cos(x), sin(x), and eˣ. This is one of the most amazing things in all of mathematics!
