derivative of y=(arctan(7x))^2

Solution

derivative of

y = (arctan (7 x))^{2}

Solution

\frac{14 arctan ( 7 x )}{49 x ^{2} + 1}

Solution steps

\frac{d}{d x} ((arctan (7 x))^{2})

Apply the chain rule:

2 arctan (7 x) \frac{d}{d x} (arctan (7 x))

= 2 arctan (7 x) \frac{d}{d x} (arctan (7 x))

\frac{d}{d x} (arctan (7 x)) = \frac{7}{49 x ^{2} + 1}

= 2 arctan (7 x) \frac{7}{49 x ^{2} + 1}

Simplify

2 arctan (7 x) \frac{7}{49 x ^{2} + 1} : \frac{14 arctan ( 7 x )}{49 x ^{2} + 1}

= \frac{14 arctan ( 7 x )}{49 x ^{2} + 1}
