limit as x approaches-2 of (x+1)/(1-x^2)

x \to - 2 lim (\frac{x + 1}{1 - x ^{2}})

\frac{1}{3}

Decimal

0.33333 \dots

Solution steps

x \to - 2 lim (\frac{x + 1}{1 - x ^{2}})

Plug in the value

x = - 2

= \frac{- 2 + 1}{1 - ( - 2 ) ^{2}}

Simplify

\frac{- 2 + 1}{1 - ( - 2 ) ^{2}} : \frac{1}{3}

= \frac{1}{3}

\frac{d}{d x} (r (x) cos (x))

\int y \cdot cos (x y) d x

n = 0 \sum \infty 1

x \to 1 lim (\frac{2}{( x - 1 ) ^{2}})

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