WebEvaluating the series at x = a, we see that. ∞ ∑ n = 0cn(x − a)n = c0 + c1(a − a) + c2(a − a)2 + ⋯ = c0. Thus, the series equals f(a) if the coefficient c0 = f(a). In addition, we … Web(a) Use differentiation to find a power series representation for f (x)= 1/ (4+x)^2 What is the radius of convergence, R? (b) Use part (a) to find a power series for f (x)=1/ (4+x)^3 What the radius of convergence, R? (c) Use part (b) to find a power series for f (x)= x^2/ (4+x)^3 What is the radius of convergence, R?
