Schritte zur Lösung

Apply the Taylor Formula

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

Evaluate Derivatives

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