# Epsilon --- Introduction ---

This is an exercise on the definition of continuity :

A function f  is continuous on a point x0, if:

For all > 0, there exists a > 0, such that |x-x0| implies |f (x)-f (x0)| .

Given a concret function (who is continuous), a x0 and a > 0, you have to find a > 0 which verifies the above condition. And you will be noted according to this : more it is close to the best possible value, better will be your note.
