Parseval-Plancherel Identity | Normalization in Quantum Mechanics
In this video, we will investigate the Parseval-Plancherel identity, which is named after the French mathematician Marc-Antoine Parseval, and the Swiss mathematician Michel Plancherel. It states that the integral over the absolute square of a function does not change after a Fourier transf

Parseval's Identity, Fourier Series, and Solving this Classic Pi Formula
To celebrate #PiDay we solve the Basel Problem - that the sum of reciprocals of square naturals is pi^2/6 - using techniques from Fourier Analysis, in particular Parseval's Identity, which is a sort of infinite dimensional analog of Pythagoras. Check out my intro playlist on FOURIER SERI

Fourier Series: Example of Parseval's Identity
Differential Equations: Find the Fourier coefficients of the square wave function f(x) = -1 on the interval (-pi, 0), 1 on the interval (0, pi). Then state Parseval's Identity in this case. With this, we show that sum 1/n^2 = pi^2/6.
