They are mentioned in the credits of the video :) This is my video series about Distributions. I hope that it will help everyone who wants to learn about it. This video is about a motivation for the theory of distributions, in particular, for the so-called delta function. 00:00 Intro 00:16 Analysis 01:30 Historical Example 03:55 Delta is not an ordinary function 06:10 Visualisation 8:00 Delta Function 9:20 Outro #Distributions #Analysis #PartialDifferentialEquations #Mathematics #LearnMath #calculus This video is about a motivation for the theory of distributions, in particular, for the so-called delta function. 00:00 Intro 00:16 Analysis 01:30 Historical Example 03:55 Delta is not an ordinary function 06:10 Visualisation 8:00 Delta Function 9:20 Outro I hope that this helps students, pupils and others.
