How come differentiation of a unit step function is Dirac Delta? Can anybody give me a concrete mathematical proof? I only found some intuitive kind of explanation, that at $t = 0$, slope of $u(t)$ increases rapidly, thus derivative at $t = 0$ becomes a Dirac Delta Function. Please give a concrete mathematical proof. Thanks.
