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

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

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

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

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

\int \frac{( 82 x + 8 )}{( 9 x + 1 ) ( x - 1 )} d x

y^{^{'}} + 2 y = 4 t, y (0) = 3

x^{- 1}

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

y^{^{''}} + 2 y^{^{'}} + 17 y = 0
