Formal definition of a limit. An epsilon-delta proof.

Limits can be found graphically, analytically, or numerically. But how are limits formally defined? In this video, I present the formal definition of a limit and then give an example of proving the limit of a linear function as x approaches a value. These are commonly referred to at epsilon-delta proofs. For an intuitive approach to limits or for basic limits and properties, I invite you to view:

u r very good at explaining and simplifying, dont know why u have so little views and subs!!
thank u.
