Is it a 'generating system' i.e does it span R? I don't know but i think the answer is yes because you can change Asinx where A is a constant to reach any point you wish..?

Those functions aren't elements of R so they certainly don't span R. Do you mean "do they span V"? For example, 1 is not in their span. [You could show this by differentiating and using independence.]
