derivative of

f (x) = \frac{7}{x}

- \frac{7}{2 x ^{\frac{3}{2}}}

Solution steps

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

Take the constant out:

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

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

Apply exponent rule:

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

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

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

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

Simplify

7 (- \frac{1}{2} x^{- \frac{1}{2} - 1}) : - \frac{7}{2 x ^{\frac{3}{2}}}

= - \frac{7}{2 x ^{\frac{3}{2}}}

\frac{sin ( x )}{cos ( x )}

\frac{d}{d t} (sin (3 ln (t) - e^{t^{2}}))

y = x^{2} - 3, (- 2, 1)

\int \frac{x ^{5} + 1}{x ^{3} - 3 x ^{2} - 10 x} d x

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