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

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

Solution steps

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

Take the constant out:

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

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

Apply exponent rule:

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

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

Apply the chain rule:

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

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

\frac{d}{d x} (3 + x) = 1

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

Simplify

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

x \to - 3 lim (\frac{x ^{3}}{x ^{2} - 9})

\frac{d}{d x} (sin (h) (x))

f (x) = e^{x}

\frac{d}{d x} (sin^{1} (x))

\frac{e ^{- 4 s}}{( 5 s ^{2} + 20 )}
