limit as x approaches-3 of sqrt(x^2-8)

x \to - 3 lim (x^{2} - 8)

1

Solution steps

x \to - 3 lim (x^{2} - 8)

Plug in the value

x = - 3

= (- 3)^{2} - 8

Simplify

(- 3)^{2} - 8 : 1

= 1

\int sec (2 x) tan (2 x) d x

\int x \cdot e^{2 x} d x

\int 2 sin (x) d x

\int cos^{3} (x) cos (3 x) d x

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