(a) Use differentiation to find a power series representation for f(x) = 1 / (2 + x)² f(x) = ? (n=0 to ?) ( ) What is the radius of convergence, R? R = 2 (b) Use part (a) to find a power series for f(x) = 1 / (2 + x)³ f(x) = ? (n=0 to ?) ( ) What is the radius of convergence, R? R = 2 (c) Use part (b) to find a power series for f(x) = x² / (2 + x)³ f(x) = ? (n=2 to ?) ( ) What is the radius of convergence, R? R = 2 Enhanced Feedback Please try again, keeping in mind that you can differentiate both sides of the power series representation of a function of the form a / (b + cx)², you may first find the
