(a) Use differentiation to find a power series representation for
f(x) = 1/(5 + x)^2
What is the radius of convergence, R?
(b) Use part (a) to find a power series for
f(x) = 1/(5 + x)^3
What is the radius of convergence, R?
(c) Use part (b) to find a power series for
f(x) = x^2 /(5 + x)^3
What is the radius of convergence, R?
