Here you learn everything about Kronecker-Delta! Including 4 calculation rules with Einstein's summation convention, typical mistakes and more.Read lesson
In this video you will learn the Kronecker delta within 10 minutes and how you can use it to write down the scalar product in index notation.
Quests with solutions
Here you practice the properties of the Kronecker delta by simplifying given expressions as much as possible.
Here you will learn the basics of differential equations (DGL), what types there are (ordinary, partial, linear, homogeneous) and 4 solving methods (separation of variables, variation of constants, exponential and separation ansatz).Read lesson
