derivative of

\frac{2}{2 x + 1}

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

Solution steps

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

Take the constant out:

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

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

Apply exponent rule:

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

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

Apply the chain rule:

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

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

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

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

Simplify

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

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

7 x + 1

\int e^{3 x} sin (7 x) d x

\int sin (8 x) cos (3 x) d x

\int_{- 1}^{4} x + 1 d x

\frac{1}{x ln ( x )}
