The formal definition of a limit is as follows: Definition We say that lim f(x) = L if, for every e > 0, we can find some d > 0 such that If(b) - L| 0 so that If (b) - | 0, we can find some 6 > 0 such that If(b) - L| 0. So let's try another! 9. Re-write the formal definition, as in # 3, using e = 0.1 So, our goal is to find S so that If (b) - ?| 0, find o such that If (b) - ?|
