derivative of f(x)=arctan(x^{10})

Solution

derivative of

f (x) = arctan (x^{10})

Solution

\frac{10 x ^{9}}{x ^{20} + 1}

Solution steps

\frac{d}{d x} (arctan (x^{10}))

Apply the chain rule:

\frac{1}{( x ^{10} ) ^{2} + 1} \frac{d}{d x} (x^{10})

= \frac{1}{( x ^{10} ) ^{2} + 1} \frac{d}{d x} (x^{10})

\frac{d}{d x} (x^{10}) = 10 x^{9}

= \frac{1}{( x ^{10} ) ^{2} + 1} \cdot 10 x^{9}

Simplify

\frac{1}{( x ^{10} ) ^{2} + 1} \cdot 10 x^{9} : \frac{10 x ^{9}}{x ^{20} + 1}

= \frac{10 x ^{9}}{x ^{20} + 1}
