## Chapter 1 - Limits and Their Properties

### Important concepts

• A limit is the value that a function "approaches" as the input "approaches" some value. Limits are essential to calculus and are used to define continuity, derivatives, and integrals.

• Limits can be found both graphically and mathematically

• One-sided limits can also be evaluated even if a limit doesn't exist

• Limits can be used to find horizontal asymptotes
