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

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

Solution steps

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

Apply the chain rule:

\frac{1}{2 arctan ( \frac{x}{2} )} \frac{d}{d x} (arctan (\frac{x}{2}))

= \frac{1}{2 arctan ( \frac{x}{2} )} \frac{d}{d x} (arctan (\frac{x}{2}))

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

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

Simplify

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

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

\int \frac{8 x ^{7} + 2 x}{x ^{8} + x ^{2}} d x

\frac{\partial}{\partial y} (\frac{2 x}{y ^{2}})

y^{^{'}} = 8 (y^{2} + 1)

\int x tan (x^{2} - 1) d x

\int x x^{2} + 8 d x
