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

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

Solution steps

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

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

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

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

\frac{d x}{d x} = 1

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

Simplify

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

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

cos (e^{x^{5} s i n (x)})

y^{^{''}} - 4 y^{^{'}} + 4 y = (18 x - 4) e^{2 x}

\frac{d y}{d t} - y cos (t) = cos (t)

\int_{0}^{l n (6)} e^{x} - e^{- 2 x} d x

\int x - 2 d x
