derivative of

x^{2} e^{- x}

2 e^{- x} x - e^{- x} x^{2}

Solution steps

\frac{d}{d x} (x^{2} e^{- x})

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x^{2}, g = e^{- x}

= \frac{d}{d x} (x^{2}) e^{- x} + \frac{d}{d x} (e^{- x}) x^{2}

\frac{d}{d x} (x^{2}) = 2 x

\frac{d}{d x} (e^{- x}) = - e^{- x}

= 2 x e^{- x} + (- e^{- x}) x^{2}

Simplify

= 2 e^{- x} x - e^{- x} x^{2}

\int_{- π}^{π} sin (m x) sin (n x) d x

(y^{2} + 4) d x - \frac{1}{( 2 x + 5 ) ^{2}} d y = 0

\int_{0}^{1} \frac{x ^{2}}{25 + x ^{2}} d x

\int \frac{3}{t ^{4}} cos (\frac{1}{t ^{3}} - 9) d t

\int_{- 8}^{8} \frac{1}{2} (64 - x^{2}) d x
