The other way, if you have a calculator, is to do it with a little bit of a table, like we've done in other example problems. So if we think about x approaching two from the positive direction, well, then we can make a little table here where you have x and then you have f of x. And so if we're approaching two from values greater than two you could have 2.1, 2.01. Now, the reason why I said calculators, these aren't trivial to evaluate because this would be, what, 2.1 over one minus cosine of 2.1 minus two is 0.1. I do not know what cosine of 0.1 is without a calculator. I do know that cosine of zero is one, so this is very, very close to one without getting to one. And it's going to be less than one.
