Facts

If the power series  a0 + a1x + a2x2 + a3x3 + … has a nonzero radius of convergence  R  and  f(x)  is the function with domain all  x  such that  | x |  < R,  f(x) being defined as the sum of the power series for  x  in that domain, then

(1)  f(x)  is continuous (at every  x  in its domain)

(2)  f(x) has a derivative  f'(x), which is the sum of the power series a1 + 2a2x + 3a3x2 +

(3)  f(x) has an indefinite integral which is given as the sum of the power series  c + a0x +  (a1/2)x2 + (a2/3)x3 + (a3/4)x4 + …

(4)  The radius of convergence for the power series in (2) and (3) is the same as that of the original power series.  [70-71]
