EXAMPLE 7 Find a power series representation for f(x) = arccot(x). SOLUTION We observe that f '(x) = -1 / (1 + x2) and find the required series by integrating the power series for -1 / (1 + x²). -1 arccot(x) = S (1 + x2) dx = s -(1 - + x4 + ...)dx = C - x + To find C, we put x = 0 and obtain C = arccot(0) = x/2. Therefore %3D = T/2 - x + 5 = A/2 - 2 (-1)" n=0 Since the radius of convergence of the series for -1/(1 + x2) is the radius of convergence of this series is also
