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

- 7 e^{- x}

Solution steps

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

Take the constant out:

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

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

Apply exponent rule:

\frac{1}{a} = a^{- 1}

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

Apply the chain rule:

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

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

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

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

Simplify

= - 7 e^{- x}

\int (1 + \frac{1}{x})^{- 2} (\frac{1}{x ^{2}}) d x

y = 9 x^{3} - x^{2} + 5 x - 6

\int e^{0.02 x} d x

\frac{d}{d x} (4 x ln (x))

\frac{d}{d x} (- cos (x) ln (sec (x) + tan (x)))
