You will be able to evaluate limits analytically using Limit Laws
What do you with a limit when direct substitution leads to the indeterminate form 0/0? You're goal is to find a function that agrees with yours at all but one point. One of the ways to accomplish that is to Factor and Cancel. Duration: 12:21
Example 10 presents another limit strategy, which requires you to Expand and Simplify. Duration: 3:18
Does your limit contain radical functions? Try Rationalizing the Numerator to resolve your indeterminate form, as we do on Example 11. Duration: 8:06
When your limit is in possession of a complex fraction, resolve the indeterminate form by Multiplying by the Common Denominator. Duration: 8:43
