Mark has 60+ answers in. Mathematics. Epsilon is just a Greek letter that's used by mathematicians when they've run out of Roman letters. Normally only the lower-case version, [math]\epsilon[/math], is used, because the upper-case version is not distinctive: E. Probably the most famous use is in the so-called epsilon-delta definition of a limit (see (Îµ, Î´)-definition of limit). Roughly, a function f(x) has the limit l as x approaches a if, for any small range delta, you can make f(x) be closer than delta to l by picking x within epsilon of a. So epsilon is sometimes used as a metaphor for a very small error range around a point.
That other number is usually called Î´ (the Greek letter delta). Such proofs are called epsilon delta proofs, and they are common in calculus and analysis, to prove the continuity of functions and various other things. Rita the dog Â· 8 years ago.
