So that's x, and that is f of x. And once again, I don't have a calculator in front of me. You could evaluate these things at a calculator, and it'll become very clear that these are positive, and as we get closer to two, they become even larger and larger positive values. And the same thing would happen if you did 1.9, and 1.9, and if you did 1.99. Because here you'd be 1.9 over one minus cosine. Now here you'd have 1.9 minus two, so this would be negative 0.1. Let me scroll over a little bit.
