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

- \frac{- x + 2}{e ^{x}}

Solution steps

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

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= \frac{\frac{d}{d x} ( 1 - x ) e ^{x} - \frac{d}{d x} ( e ^{x} ) ( 1 - x )}{( e ^{x} ) ^{2}}

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

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

= \frac{( - 1 ) e ^{x} - e ^{x} ( 1 - x )}{( e ^{x} ) ^{2}}

Simplify

\frac{( - 1 ) e ^{x} - e ^{x} ( 1 - x )}{( e ^{x} ) ^{2}} : - \frac{- x + 2}{e ^{x}}

= - \frac{- x + 2}{e ^{x}}

\frac{\partial}{\partial x} (- y cos (- 3 x))

n = 2 \sum \infty \frac{( n - 1 )}{n}

- x^{4} + 2 x^{3} + 4 x^{2}

f (x) = 3 x^{2} + 2

\int 2^{l n (x)} d x
