derivative of

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})

f (x) = 100 - x^{2}, at x = - 6

t sin (1.74 t)

\int - \frac{1}{3 ( s - 1 ) ^{3}} d s

\int \frac{x}{x - 13} d x

\int cos^{4} (3 x) d x
