I am having difficulty understand why 0<=t<1. The proof says, "positive real numbers t such that.." Earlier (when it states the theorem) it also says x >0, so how is it possible that t is 0? Shouldn't it be 0<t<1? By the way this is my first time asking a question on here, so I don't know if my file got attached correctly.

You are correct, but it doesn't matter as far as the proof is concerned.

Okay, thank you. I understand the proof still works. I just wanted clarification on that part.
