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

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

Solution steps

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

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply the common derivative:

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

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

Simplify

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

= \frac{4}{x ^{2} + 1}
