Mathematics

Illustrated overview of all geometric solids with important properties as well as formulas for areas, volumes and other quantities.

Here you will learn by example what the difference is between the partial derivative and the total derivative.

Proof of the two Green's identities (formulas) using the Gauss integral theorem, which are useful in the calculation of some electric potentials.

In this video you will learn what Fourier series / coefficients are and how to specify / calculate them for a function.

Here you will learn what a Fourier series is, how it can be calculated, and the role of Fourier coefficients and basis functions.
