Precise Definition of Infinite Limits at Infinity: Example
In this video I go over a useful example to better illustrate the precise definition of infinite limits at infinity. The example I go over is a math proof using the precise definition of the limit as x approaches infinity of the function f(x) = 1 + x3 and proving it is equal to infinity.

Recap on Precise Definition:
Let f be a function defined on some interval (a, ∞). Then:
means that for every positive number M there is a corresponding positive number N such that:
