Part 1 Use differentiation and/or integration to express the following function as a power series (centered at x = 0). f(x) = 1 (4 + x)2 f(x) = Σ n=0 Part 2 Use your answer above (and more differentiation/integration) to now express the following function as a power series (centered at x = 0). g(x) = 1 (4+ x)3 g(x) = $ n=0 Part 3 Use your answers above to now express the function as a power series (centered at 2 = 0). 72 h(2) = (4 + x)3 h(x) = n=0
