After completing this section, you should be able to do the following.

Identify whether a particular limit can be evaluated using the limit laws.
Calculate limits using the limit laws.
Explain the idea behind the Squeeze Theorem and how it can be used to find limit values.
Calculate limits using the Squeeze Theorem.
Use the fact that $\lim _{x \to 0} \frac {\sin x}{x} = 1$ to evaluate limits.

Skills you may want to brush up on first
To be ready to achieve these objectives, you may need to review the following trigonometry and algebra topics:

Trigonometric Functions (especially the definitions of the 6 trigonometric functions and the unit circle)
