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

x \to 4 lim (x^{2} + 9)

f (x) = (5 + x^{4})^{3 x}

\frac{\partial}{\partial y} (x^{3} + k y^{2} - 5 x y)

\frac{d}{d x} ((x^{2} - 7)^{2})
