But now for the limit purposes, you could say this limit is going to be the limit as x approaches zero of one over two cosine of x. And now we can go back to this green condition right over here, because we can evaluate this at x equals zero. It's gonna be one over two times cosine of zero. Cosine of zero is one. So this is going to be equal to 1 1⁄2. Now in general, none of these techniques work. And you'll encounter a few other techniques further on once you learn more calculus.
