derivative of (arctan(9x)^2)

Solution

\frac{d}{d x} ((arctan (9 x))^{2})

Solution

\frac{18 arctan ( 9 x )}{81 x ^{2} + 1}

Solution steps

\frac{d}{d x} ((arctan (9 x))^{2})

Apply the chain rule:

2 arctan (9 x) \frac{d}{d x} (arctan (9 x))

= 2 arctan (9 x) \frac{d}{d x} (arctan (9 x))

\frac{d}{d x} (arctan (9 x)) = \frac{9}{81 x ^{2} + 1}

= 2 arctan (9 x) \frac{9}{81 x ^{2} + 1}

Simplify

2 arctan (9 x) \frac{9}{81 x ^{2} + 1} : \frac{18 arctan ( 9 x )}{81 x ^{2} + 1}

= \frac{18 arctan ( 9 x )}{81 x ^{2} + 1}
