I'm trying to find the limit of this function as x tends to 0 but I'm completely unsure of how to proceed. I can't seem to find any identities that would allow me remove the denominator. Any idea about how to go about it?

As this is an indeterminate form at the limit (0/0) you are probably expected to use L'hopital's rule.
An alternative is to try small angle approximations.
