Question

write the Euler's formula for the fourier series expansion of a function f(x)in the
interval (0,2π)​

Answer 1

Answer: V = E + 2

Step-by-step explanation:

Euler's formula, Either of two important mathematical theorems of Leonhard Euler. The first is a topological invariance (see topology) relating the number of faces, vertices, and edges of any polyhedron. It is written F + V = E + 2, where F is the number of faces, V the number of vertices, and E the number of edges
