derivative of

- \frac{8}{( 1 + 4 x ) ^{2}}

\frac{64}{( 1 + 4 x ) ^{3}}

Solution steps

\frac{d}{d x} (- \frac{8}{( 1 + 4 x ) ^{2}})

Take the constant out:

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

= - 8 \frac{d}{d x} (\frac{1}{( 1 + 4 x ) ^{2}})

Apply exponent rule:

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

= - 8 \frac{d}{d x} ((1 + 4 x)^{- 2})

Apply the chain rule:

- \frac{2}{( 1 + 4 x ) ^{3}} \frac{d}{d x} (1 + 4 x)

= - \frac{2}{( 1 + 4 x ) ^{3}} \frac{d}{d x} (1 + 4 x)

\frac{d}{d x} (1 + 4 x) = 4

= - 8 (- \frac{2}{( 1 + 4 x ) ^{3}} \cdot 4)

Simplify

- 8 (- \frac{2}{( 1 + 4 x ) ^{3}} \cdot 4) : \frac{64}{( 1 + 4 x ) ^{3}}

= \frac{64}{( 1 + 4 x ) ^{3}}

\int \frac{1}{2} + \frac{1}{2} cos (2 x) d x

\int_{1}^{2} (x^{4} + \frac{1}{4 x ^{4}}) d x

x^{4} - 2 x^{4}

\int \frac{x}{x ^{2} + x - 2} d x

\int - 3 x e^{- 3 x} d x
