Then I will find you a delta. So let me write this in a little bit more math notation. So I'll write the same exact statements with a little bit more math here, but it's the exact same thing. So you give me, or let me write it this way. Given an epsilon greater than 0, we can find, so that's kind of the first part of the game, we can find a delta greater than 0 such that if x is within delta of c. So what's another way of saying that x is within delta of c? Well, one way you could say, well, what's the distance between x and c is going to be less than delta. This statement is true for any x that's within delta of c. The difference between the two is going to be less than delta.
