Convolutions and Polynomial Approximation

Описание к видео Convolutions and Polynomial Approximation

In this video, I intuitively explain and apply some deeper mathematical tools - namely convolutions and approximate identities - to prove the Weierstrass approximation theorem, which roughly states that any continuous function can be approximated by polynomials. I also make connections to other examples where approximate identities show up, like the Gaussian blur and moving averages. Some familiarity with calculus is recommended, but not required.
