derivative of

y = \frac{7}{x + 5}

- \frac{7}{2 ( x + 5 ) ^{\frac{3}{2}}}

Solution steps

\frac{d}{d x} (\frac{7}{x + 5})

Take the constant out:

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

= 7 \frac{d}{d x} (\frac{1}{x + 5})

Apply exponent rule:

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

= 7 \frac{d}{d x} ((x + 5)^{- \frac{1}{2}})

Apply the chain rule:

- \frac{1}{2 ( x + 5 ) ^{\frac{3}{2}}} \frac{d}{d x} (x + 5)

= - \frac{1}{2 ( x + 5 ) ^{\frac{3}{2}}} \frac{d}{d x} (x + 5)

\frac{d}{d x} (x + 5) = 1

= 7 (- \frac{1}{2 ( x + 5 ) ^{\frac{3}{2}}} \cdot 1)

Simplify

7 (- \frac{1}{2 ( x + 5 ) ^{\frac{3}{2}}} \cdot 1) : - \frac{7}{2 ( x + 5 ) ^{\frac{3}{2}}}

= - \frac{7}{2 ( x + 5 ) ^{\frac{3}{2}}}

\int (x - 4)^{2} d x

x \to 0 + lim ((x + 1)^{I n x})

\int \frac{( ln ( x ) )}{x ^{3}} d x

\frac{d v}{d t} = - k v

\frac{d y}{d x} - \frac{7 y}{x} = \frac{y ^{3}}{x ^{9}}
