Question

state dirichlet condition

Answer 1

In mathematics, the Dirichlet conditions are sufficient conditions for a real-valued,periodic function f to be equal to the sum of its Fourier series at each point where f is continuous

Answer 2

A piecewise regular function that

1. Has a finite number of finite discontinuities and

2. Has a finite number of extrema

can be expanded in a Fourier series which converges to the function at continuous points and the mean of the positiveand negative limits at points of discontinuity.
