lim x->0 [tex](1-cosx)/sinx[/tex]
[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.
