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

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

Solution steps

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

Apply exponent rule:

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

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

Apply the chain rule:

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

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

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

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

Simplify

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

arctan (\frac{x}{2})

x \to \infty lim ((ln (x))^{\frac{1}{x ^{2}}})

\int x^{4} in (x) d x

y^{^{'}} + a^{2} y = 0

\frac{\partial}{\partial x} (- 2 sin (2 x) - 2 x e^{5 y})
