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

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

- \frac{1}{2}

Decimal Notation

- 0.5

Solution steps

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

Simplify

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

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

Plug in the value

x = 1

= - \frac{1}{1 + 1}

Simplify

= - \frac{1}{2}

\int x^{4} sin (2 x) d x

f (x) = arcsin (6 x^{4})

n = 1 \sum \infty n e^{n}

\int_{2}^{5} t^{3} ln (5 t) d t

\frac{d}{d x} ((x - 1) (x - 2) (2 - x^{2}))
