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. Cosine is never going to be greater than one. The cosine function is bounded between negative one is less than cosine of x. I'll just write the x there, I don't need the parentheses, which is less than one. The cosine function just oscillates between these two values.
