derivative of

arctan (\frac{x}{4})

\frac{4}{x ^{2} + 16}

Solution steps

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

Apply the chain rule:

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

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

\frac{d}{d x} (\frac{x}{4}) = \frac{1}{4}

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

Simplify

\frac{1}{( \frac{x}{4} ) ^{2} + 1} \cdot \frac{1}{4} : \frac{4}{x ^{2} + 16}

= \frac{4}{x ^{2} + 16}

\int \frac{( 4 - x ) ^{2}}{x} d x

\frac{e ^{x}}{e ^{x} + 3}

\frac{d y}{d x} = 2 x e^{- y}

\int \frac{4 x}{x ^{2} + 1} d x

\int x^{2} \cdot 2^{x} d x
