limit as x approaches-4-of 1/(x^2-16)

x \to - 4 - lim (\frac{1}{x ^{2} - 16})

\infty

Solution steps

x \to - 4 - lim (\frac{1}{x ^{2} - 16})

For

x

approaching

- 4

from the left

, x < - 4 \Rightarrow x^{2} - 16 > 0

The denominator is a positive quantity approaching 0 from the right

= \infty

\frac{\partial}{\partial x} (1 + x^{2} + y^{2})

\frac{d}{d x} (e^{- \frac{x}{t}})

\int \frac{1}{x ( x + 1 ) ^{2}} d x

e^{\frac{( - x ^{2} )}{4}}

n = 1 \sum \infty \frac{1}{n} + \frac{1}{n ^{2}}
