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

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

\infty

Solution steps

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

For

x

approaching

- 2

from the left

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

The denominator is a positive quantity approaching 0 from the right

= \infty

\frac{d}{d x} (\frac{1}{cosh ( x )})

x \to 3 lim (\frac{10}{x - 3})

h = t^{2} (6 t - 4)^{3}

\frac{\partial}{\partial x} (3 ln (x) - 5)

\int \frac{x - 17}{x ^{2} + 1} d x
