I'll do (a)...

But this is not the same as your linear function y = 1. is going to look like a horizontal line with some "holes". The domain of f(x) = cos(x) is all real numbers, but the domain of g(x) = csc(x)tan(x) is all reals except multiples of pi/2. So the domain of is the intersection of the two domains, or all reals except multiples of pi/2.
