(a) Use differentiation to find a power series representation for f( x ) = (2 + x ) 2 " f (x ) = n = 0 What is the radius of convergence, R? R = 2 (b) Use part (a) to find a power series for 1 f(x ) = (2 + X) 3 F( x ) =/ n = 0 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 ) = Z( n = 2 What is the radius of convergence, R? R = 2
