What is the domain of #f(x)=cscx#?
Being a fraction, we have to make sure that the denominator is non-zero; and since there are no roots or logarithms, it is the only thing we have to study.

The domain of ( f(x) = \csc(x) ) is ( x \neq k\pi ), where ( k ) is an integer, because the cosecant function is undefined at points where the sine function is zero. Therefore, the domain of ( f(x) = \csc(x) ) is ( x \neq k\pi ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
