derivative of

- arctan (x)

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

Solution steps

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

Take the constant out:

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

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

Apply the common derivative:

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

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

\int \frac{x e ^{5 x}}{( 5 x + 1 ) ^{2}} d x

x \to 0 lim (e^{\frac{∣ x ∣}{x}})

cos^{2} (x)

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

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