In this lesson, we will be discussing how to use limit rules and find limits of different functions. The functions we will discuss are the following:
1. Reciprocal Functions
2. Exponential Functions
3. Logarithmic Functions
4. Trigonometric Functions
5. Square Root Functions – this will not be discussed because you can use the Plug-In method OR multiply by the conjugate because there is a square root in this equation. This was discussed in my post on solving limits using conjugates.
Here are common trig identities to use in manipulating your equations:
Here are the limit rules:
And here are some important limit to just straight up memorize:
