44. Suppose that f is a continuous function for t > 0 and is of exponential order. (a) If f(t) → F (s) is a transform pair, prove that F (s) f (t) dt} (s) = L Hint: Let g(t) = S f(t) dt. Then note that g'(t) f (t) and use Proposition 2.1 to compute L{g'(t)}(s). (b) Use the technique suggested in part (a) to find 1 -1 L s (s² + 1)
