derivative of

y = 2 x^{3} e^{- x}

2 (3 e^{- x} x^{2} - e^{- x} x^{3})

Solution steps

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

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 2 \frac{d}{d x} (x^{3} e^{- x})

Apply the Product Rule:

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

f = x^{3}, g = e^{- x}

= 2 (\frac{d}{d x} (x^{3}) e^{- x} + \frac{d}{d x} (e^{- x}) x^{3})

\frac{d}{d x} (x^{3}) = 3 x^{2}

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

= 2 (3 x^{2} e^{- x} + (- e^{- x}) x^{3})

Simplify

= 2 (3 e^{- x} x^{2} - e^{- x} x^{3})

\frac{d}{d x} (a b^{2} - x^{2})

\frac{d}{d x} (x - \frac{1}{x})

\int \frac{2 + x ^{2}}{4 - x ^{4}} d x

\int 49 tan^{5} (x) sec^{4} (x) d x

h \to 0 + lim (2 + h)
