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

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

- \frac{1}{2}

Decimal

- 0.5

Solution steps

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

Simplify

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