Schritte zur Lösung

Apply the Taylor Formula

= \frac{1}{2} + \frac{\frac{d}{d x} ( \frac{1}{1 - x} ) ( - 1 )}{1 !} (x + 1) + \frac{\frac{d ^{2}}{d x ^{2}} ( \frac{1}{1 - x} ) ( - 1 )}{2 !} (x + 1)^{2} + \frac{\frac{d ^{3}}{d x ^{3}} ( \frac{1}{1 - x} ) ( - 1 )}{3 !} (x + 1)^{3} + \dots

Evaluate Derivatives

= \frac{1}{2} + \frac{\frac{1}{4}}{1 !} (x + 1) + \frac{\frac{1}{4}}{2 !} (x + 1)^{2} + \frac{\frac{3}{8}}{3 !} (x + 1)^{3} + \frac{\frac{3}{4}}{4 !} (x + 1)^{4} + \dots
