taylor

x^{2} e^{- x}

x^{2} - x^{3} + \frac{1}{2} x^{4} - \frac{1}{6} x^{5} + \frac{1}{24} x^{6} + \dots

Solution steps

Apply the Taylor Formula

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

Evaluate Derivatives

= 0 + \frac{0}{1 !} x + \frac{2}{2 !} x^{2} + \frac{- 6}{3 !} x^{3} + \frac{12}{4 !} x^{4} + \frac{- 20}{5 !} x^{5} + \frac{30}{6 !} x^{6} + \dots

Refine

= x^{2} - x^{3} + \frac{1}{2} x^{4} - \frac{1}{6} x^{5} + \frac{1}{24} x^{6} + \dots

\frac{d}{d x} (\frac{- 2}{9 x ^{\frac{5}{3}}})

\int_{6}^{7} \frac{x}{x ^{2} + 4 x + 13} d x

\frac{\partial}{\partial y} (7 (x + 5 y - 4)^{2})

\int_{- 2}^{2} (4 x^{3} + 6 x^{2} - 8 x + 5) d x

\int 2400 x 3 + 2 x d x
