Limit and Conjugate Method Concepts

In this video, Mike from Arnold Tutoring explains how to solve calculus limits when X approaches a number, not infinity. He introduces three methods: factor and cancel, conjugate, and handling fractions within fractions. Each method involves algebraic manipulation to eliminate problems like zero denominators. The video provides step-by-step examples for each method, helping students understand how to apply these techniques to solve limits effectively.
