Sometimes, solving a limit on a function involving
trigonometric functions is simply a matter of remembering some of
the basic trig identities. That is the approach we use to evaluate:

$\underset{x\to 0}{lim}\frac{cos\mathrm{(x)}}{sin\mathrm{(x)}-2}$

$\underset{x\to 0}{lim}\frac{cos\mathrm{(x)}}{sin\mathrm{(x)}-2}$
