In this video you will first learn what the Dirac delta function is good for and how to represent it graphically. Then we will look at what the delta function does in a product with another function in the integral.

Then we move to a shifted delta function and its integral. Then we prove that the Dirac delta is symmetric and what it yields when scaled by a factor in the argument.

To better understand their derived properties, we make three examples. And in the end we consider a three-dimensional delta function.
