The Gamma function often appears in engineering applications and differential equations, including Laplace transforms. It is defined, for a > 0, by T(x) = √e-¹²-¹ dt. (a) Show that I'(x + 1) = xF(x), for x > 0. (b) Show that I(1) = 1. (c) Show that {tº } = r(a + 1) sª+1 , for a > -1 and s> 0. (d) Find {1¹/2}. Remark 1: It can be deduced that I'(n+1) = n! for n a positive integer. For this reason, the gamma function is often called the factorial function. Remark 2: Referring to part (c), note that if n is a nonnegative integer, then n! for s> 0. 8"+1" Remark 3: Using Calculus III, we can show that I' Laplace transforms.
