Hint: Polynomial functions, exponential functions and sine/cosine functions are defined for all values of x. That means that so is their sum, difference, product and composition, and their quotients will be defined for all values of x except where the denominator is 0.

I'm not really sure what to do here still :S

I gave you a very big hint. They will be defined everywhere except where the denominators are 0.
