You could think of this as f of x is equal to, you could view this as f of theta is equal to one, g of theta is equal to this, and h of theta is equal to that. And over the interval that we care about, we could say four, negative pi over two is less than theta, is less than pi over two. But over this interval, this is true for any theta over which these functions are defined. Sine of theta over theta is defined over this interval except where theta is equal to zero. But since we're defined everywhere else, we can now find the limit. So what we can say is, well, by the squeeze theorem or by the sandwich theorem, if this is true over the interval, then we also know that the following is true. And this we deserve a little bit of a drum roll.
