derivative of

arctan (x^{4})

\frac{4 x ^{3}}{x ^{8} + 1}

Solution steps

\frac{d}{d x} (arctan (x^{4}))

Apply the chain rule:

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

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

\frac{d}{d x} (x^{4}) = 4 x^{3}

= \frac{1}{( x ^{4} ) ^{2} + 1} \cdot 4 x^{3}

Simplify

\frac{1}{( x ^{4} ) ^{2} + 1} \cdot 4 x^{3} : \frac{4 x ^{3}}{x ^{8} + 1}

= \frac{4 x ^{3}}{x ^{8} + 1}

y = \frac{1}{x + 1} + 1

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

y^{^{''}} + 2 y^{^{'}} + 5 y = e^{- x} sec (2 x)

\frac{d ^{2}}{d x ^{2}} (6 csc (x))

\frac{d}{d x} (x sinh (x^{2}))
