limit as x approaches-2-of (-2)/(x^2-4)

x \to - 2 - lim (\frac{- 2}{x ^{2} - 4})

- \infty

Solution steps

x \to - 2 - lim (\frac{- 2}{x ^{2} - 4})

For

x

approaching

- 2

from the left

, x < - 2 \Rightarrow x^{2} - 4 > 0

The denominator is a positive quantity approaching 0 from the right

= - \infty

\frac{d}{d x} (A sin (2 x) + B cos (2 x))

y = 12 cos (x)

\frac{d}{d t} (k t)

\int_{- 1}^{3} 6 x^{2} d x

e^{- x^{2}}
