derivative of

\frac{7 x}{e ^{x}}

\frac{7 ( 1 - x )}{e ^{x}}

Solution steps

\frac{d}{d x} (\frac{7 x}{e ^{x}})

Take the constant out:

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

= 7 \frac{d}{d x} (\frac{x}{e ^{x}})

Apply the Quotient Rule:

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

= 7 \cdot \frac{\frac{d x}{d x} e ^{x} - \frac{d}{d x} ( e ^{x} ) x}{( e ^{x} ) ^{2}}

\frac{d x}{d x} = 1

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

= 7 \cdot \frac{1 \cdot e ^{x} - e ^{x} x}{( e ^{x} ) ^{2}}

Simplify

7 \cdot \frac{1 \cdot e ^{x} - e ^{x} x}{( e ^{x} ) ^{2}} : \frac{7 ( 1 - x )}{e ^{x}}

= \frac{7 ( 1 - x )}{e ^{x}}

\frac{d}{d x} (8^{- 3 x^{2}})

x \to 5 + lim (- ln (5 - x))

e^{- 2 t} sin (3 t)

\frac{\partial}{\partial x} (x^{3} + 3 x y^{2})
