derivative of

2 arctan (x)

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

Solution steps

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

Take the constant out:

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

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

Apply the common derivative:

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

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

Simplify

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

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

x \to - 3 lim (7 x^{2})

\int x e^{5 x^{2}} d x

x^{2} + x y + 2 y^{2} = 4

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