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

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

- 2

Solution steps

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

Simplify

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

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

Plug in the value

x = 1

= - 1 - 1

Simplify

= - 2

y = \frac{2}{x - 8} (10.1)

n = 1 \sum \infty \frac{1}{n ^{\frac{1}{3}}}

\int \frac{3}{5 x ^{2}} d x

\frac{d}{d x} (x - 7 3 x)

\frac{3 ( 1 - 4 x )}{58 ( x ^{2} + 9 )}
