derivative of

\frac{5}{x + 9}

- \frac{5}{2 ( x + 9 ) ^{\frac{3}{2}}}

Solution steps

\frac{d}{d x} (\frac{5}{x + 9})

Take the constant out:

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

= 5 \frac{d}{d x} (\frac{1}{x + 9})

Apply exponent rule:

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

= 5 \frac{d}{d x} ((x + 9)^{- \frac{1}{2}})

Apply the chain rule:

- \frac{1}{2 ( x + 9 ) ^{\frac{3}{2}}} \frac{d}{d x} (x + 9)

= - \frac{1}{2 ( x + 9 ) ^{\frac{3}{2}}} \frac{d}{d x} (x + 9)

\frac{d}{d x} (x + 9) = 1

= 5 (- \frac{1}{2 ( x + 9 ) ^{\frac{3}{2}}} \cdot 1)

Simplify

5 (- \frac{1}{2 ( x + 9 ) ^{\frac{3}{2}}} \cdot 1) : - \frac{5}{2 ( x + 9 ) ^{\frac{3}{2}}}

= - \frac{5}{2 ( x + 9 ) ^{\frac{3}{2}}}

\frac{d}{d x} (a (t - sin (t)))

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

\int_{- 4}^{12} z + 4 d z

x \to 4 lim (x^{2} + 7 - x)

x^{2} y^{^{''}} - 16 x y^{^{'}} + 72 y = 0
