Schritte zur Lösung

Apply the Taylor Formula

= 0 + \frac{\frac{d}{d x} ( x sin ( x ) ) ( 0 )}{1 !} x + \frac{\frac{d ^{2}}{d x ^{2}} ( x sin ( x ) ) ( 0 )}{2 !} x^{2} + \frac{\frac{d ^{3}}{d x ^{3}} ( x sin ( x ) ) ( 0 )}{3 !} x^{3} + \dots

Evaluate Derivatives

= 0 + \frac{0}{1 !} x + \frac{2}{2 !} x^{2} + \frac{0}{3 !} x^{3} + \frac{- 4}{4 !} x^{4} + \frac{0}{5 !} x^{5} + \frac{6}{6 !} x^{6} + \frac{0}{7 !} x^{7} + \frac{- 8}{8 !} x^{8} + \frac{0}{9 !} x^{9} + \frac{10}{10 !} x^{10} + \dots
