How to find Limits

This video looks at different methods for finding limits of functions.
SUBSTITUTION
It first looks at the substitution method and demonstrates this method using two examples. It then demonstrates why the substitution method won't always work.
FACTOR
It explains how and when to use the factor method when the substitution method will not work. It does this using two examples.
CONJUGATE
The final method it looks at is the conjugate method when the substitution method fails and when radicals are involved in the function. It uses a further two examples to demonstrate this method.
WHERE THE LIMIT DOES NOT EXIST
In some cases limits of functions do not exist. The video demonstrates using three examples of this case.
