Verify the product rule for Formal Power Series. Very specifically: Let f(x) be the generating function for a sequence san) and g(x) be the generating function for a sequence sbn1. Using the definitions of multiplication and differentiation of FPS, write down a formula for the derivative of [f(x)g(x)]. Then write down a formula for f(x)g(x) + f(x)g'(x), where f(x) denotes the derivative of f(x). Then show that the two formulas describe the same formal power series. (i.e. both series have...
