خطوات الحلّ

Apply the Taylor Formula

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

Evaluate Derivatives

= 0 + \frac{1}{1 !} x + \frac{- 2}{2 !} x^{2} + \frac{- 1}{3 !} x^{3} + \frac{12}{4 !} x^{4} + \frac{- 59}{5 !} x^{5} + \dots
