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.
