Question

find the fourier series of the function f(x) e^−x = in the interval −π<x<π​

Answer 1

Step-by-step explanation:

Basic Definitions

A function f(x) is said to have period P if f(x+P)=f(x) for all x. ...

If the conditions 1 and 2 are satisfied, the Fourier series for the function f(x) exists and converges to the given function (see also the Convergence of Fourier Series page about convergence conditions.)
