And I know what a lot of you are thinking, Sal, this seems like a very, you know, why don't I just, you know, do this algebra here, cross these things out, and just substitute zero for theta? Well, you could do that, and you would get the answer, but you need to be clear, or it's important to be mathematically clear of what you are doing. If you do that, if you just cross these two out, and all of a sudden, your expression becomes defined at zero, you are now dealing with a different expression, or a different function definition. So to be clear, if you want to say this is the function you're finding the limit of, you have to put this constraint in to make sure it has the exact same domain. But lucky for us, we can say if we found another function that's continuous at that point that doesn't have that gap there, that doesn't have that point discontinuity out, the limits are going to be equivalent. So the limit as theta approaches zero of g of x, well, that's just going to be, since it's continuous at zero, we could say that's just going to be, we can just substitute, that's going to be equal to g of zero, which is equal to one over two plus cosine two, one over two plus two times cosine of zero. Cosine of zero is one, so it's just one over two plus two, which is equal to, deserve a little bit of a drum roll here, which is equal to 1 4th.
