This is not always recognized since Cauchy gave a purely verbal definition of limit which at first glance does not resemble modern definitions.

Definition of derivative epsilon delta. In the first section of the Limits chapter we saw that the computation of the slope of a tangent line the instantaneous rate of change of a function and the instantaneous velocity of an object at x a all required us to compute the following limit. The Definition of the Derivative. But what you would presumably do using epsilon and delta is to expand to give subtract f x from it giving and then dividing by giving.

Lim xa fx L if for every number 0 there is a corresponding number 0 such that 0. In calculus Epsilon is a tiny number close to zero. The definition gives us the limit L of a function f x defined on a certain interval as x approaches some number x 0.
