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

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

\infty

Solution steps

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

For

x

approaching

1

from the left

, x < 1 \Rightarrow x^{2} - 1 < 0

The denominator is a negative quantity approaching 0 from the left

= \infty

\frac{\partial}{\partial x} (8 x^{2} - 4 x y - 3 x^{2} y)

2 ln (cos (t))

x \to \infty lim (arctan (x))

\frac{d}{d x} (\frac{sin ( x ^{3} )}{x ^{2}})

- 2 t^{3} δ (t - 4)
