Schritte zur Lösung

Apply the Taylor Formula

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

Evaluate Derivatives

= e - 1 + \frac{2}{1 !} (x - 1) + \frac{2 ( 2 e - 3 )}{2 !} (x - 1)^{2} + \frac{4 ( - e + 6 )}{3 !} (x - 1)^{3} + \frac{4 ( 15 e - 30 )}{4 !} (x - 1)^{4} + \dots
