## Homework Statement

Mod note: Edited the following to fix the LaTeX[/B]

compute

##\lim_{n \rightarrow +0} \frac {8-9cos x+cos 3x} {sin^4(2x)}##

##\lim_{n \rightarrow +\infty} \frac {\sin(x)} x##

##\lim_{n \rightarrow +\infty} \frac {\sin(x)} x##

ok find limit as x→0 for the function ##[ 8-9cos x + cos 3x/{sin^4}2x]##

## Homework Equations

## The Attempt at a Solution

use Lhopital rule...
