DIRAC DELTA FUNCTION AS A DISTRIBUTION
as the integral of the limit of the integrand.The integral has the value 1 for every σ> 0, so the limit of the integral as σ → 0 is 1.However, if one takes the limit of the integrand first, and then integrates, the answer is zero. Dirac Delta Function as a Distribution: A Dirac delta function is defined to have the property that d ∞ − ...

Using the definition of a Dirac Delta function given in equation (9), prove that the Dirac Delta function has to be normalized. i.e. prove: Z ∞ −∞ δ(x)dx = 1 Another way that you can think of the Dirac Delta function is as the deriva-tive of the step (Heaviside) function, H(x).
