Then we have what is known as an impulsive force, and for m(t) = 1 (unit force) we have t0 f (t) dt = 1. 1), and one such function is f (t) = F (t) = 1 . Using this function, let 2t0  0 if t0 < |t|, 1  2t0 if t0 ≥ |t|. 2) This function F (t) is an ordinary function which belongs to the class C0∞ (I), where I = [−t0 ≤ t ≤ t0 ]. However, F (t) → δ(t) as t0 → 0; that is, in the limit as t0 → 0 the function F (t) converges to the Dirac delta-function (henceforth written δ-function)1 which is not a function in the ordinary sense; it is called a generalized function.

1), but their areas remain constant, since fε (t) dt = 1 for any ε > 0. This means that the δ-function can be defined as the limit δ(t) = lim fε (t). Obviously, this limit is zero everywhere ε→0 except at the point t = 0. 8) subject to the additional normalization condition that the area under this function is equal to 1. fε(t ) 0 ε t Fig. 1.
