taylor e^x*sin(x)

taylor

e^{x} \cdot sin (x)

x + x^{2} + \frac{1}{3} x^{3} - \frac{1}{30} x^{5} - \frac{1}{90} x^{6} + \dots

Solution steps

Apply the Taylor Formula

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

Evaluate Derivatives

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

Refine

= x + x^{2} + \frac{1}{3} x^{3} - \frac{1}{30} x^{5} - \frac{1}{90} x^{6} + \dots
