limit as x approaches-1 of arctan(x)

x \to - 1 lim (arctan (x))

- \frac{π}{4}

Decimal Notation

- 0.78539 \dots

Solution steps

x \to - 1 lim (arctan (x))

Plug in the value

x = - 1

= arctan (- 1)

Simplify

arctan (- 1) : - \frac{π}{4}

= - \frac{π}{4}

\frac{d}{d x} (arcsinh (\frac{2 x + 5}{23}))

\frac{d}{d x} (- 3 x)

- \frac{8}{x ^{2}} - \frac{8}{x}

\int_{2}^{3} \frac{20}{3 - x} d x
