derivative of

f (x) = arctan (x)

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

Solution steps

\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{1}{sin ( θ )} d θ

\int \frac{1}{3 x - 3} d x

\int_{4}^{6} \frac{x}{x ^{2} + 6 x + 13} d x

x^{2} 9 - x^{2}

x \to 2 lim (2 x^{3} + 4 e^{x})
