derivative of

arctan (8 x^{2} - 1)

\frac{1}{x 8 x ^{2} - 1}

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

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

= \frac{1}{x 8 x ^{2} - 1}

\frac{\partial}{\partial x} (\frac{1}{sin ( x ^{2} - y ^{2} )})

6 x

y^{^{''}} + a = 0

x y^{^{'}} + 2 y = \frac{( 3 e ^{- 3 x} )}{x}

f^{^{'}} (x) = x^{4}
