## Homework Statement

lim

_{x->0 }[tex](1-cosx)/sinx[/tex]

## Homework Equations

[tex](sinx)/(1+cosx)[/tex] = [tex](1-cosx)/(sinx)[/tex]

[tex]sinx/x[/tex] = 1

## The Attempt at a Solution

Well, I know I need to change my original limit, as I cannot let the denominator be 0. I usually try to factor out things, but there is nothing to factor out here. I'm not really sure what to do.
