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

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

- 2

Solution steps

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

Simplify

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

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

Plug in the value

x = 1

= - 1 - 1

Simplify

= - 2

\int \frac{1}{x 4 x ^{4} - 1} d x

\int_{- 2}^{1} (- x^{2} - x + 2) d x

\int 3 25 - x d x

\int_{- 2}^{0} (7 x^{2} + 7 x) d x

\int 2 sin (t) d t
