Calculus - Limits (Epsilon Delta Proofs): Limit of a Quadratic (Example 1) - Part 1
Показать описание
In this video, we present an Epsilon-Delta proof for the calculation of the Limit associated with a Quadratic. The proof requires that we first find an appropriate delta and then proceed to show that |f(x) - L| is less than the given epsilon. In dealing with a quadratic finding the appropriate delta results in a value dependent on both epsilon and x. Restricting delta results in two possible values and two cases, which we present.
