Introduction to the Number Line
Description
A detailed tutorial on the number line. Step by step tutorial including several examples of when and how use the number line for reference.
Overview
The number line is a basic concept in math that helps to visualize where all the numbers are. On a traditional number line, the number zero is placed in the middle, with numbers going up by one lining either side (the left side is negative, the right side is positive). The number line stretches to infinity in both directions. The number line is used when first learning math to assist with addition and subtraction. The number line is brought up again in algebra, to help with inequalities. Often inequalities are graphed on the number line, to show possible values of the variable given.

How to Find Horizontal Asymptotes
Description
A detailed tutorial on how to find horizontal asymptotes. Step by step tutorial including several examples of how to find horizontal asymptotes for reference.
Overview
There are several different types of asymptotes. In this tutorial, we will be discussing horizontal asymptotes. In order to find the horizontal asymptotes of a function, take the limit of the function to infinity. Every function has a horizontal asymptote if it has a limit to infinity. The limit is your horizontal asymptote.

How to Find Vertical Asymptotes
Description
A detailed tutorial on how to find vertical asymptotes. Step by step tutorial including several examples of how to find vertical asymptotes for reference.
Overview
There are several different types of asymptotes. In this tutorial, we will be discussing vertical asymptotes. In order to find the vertical asymptotes of a function, we must first determine if there is a vertical asymptote. There is only a vertical asymptote if the limit of the function is equal to positive or negative infinity. If that is true, then the limit will reveal the vertical asymptote.

An Overview of l’Hôpital’s Rule
Description
This video explains how to properly use l’Hôpital’s Rule and tells us why it is sometimes necessary to use l’Hôpital’s Rule instead of another method of finding the limit. This video also gives several example problems of how to use l’Hôpital’s Rule.
Overview
l’Hôpital’s Rule is a rule of calculus that helps when evaluating the limit to infinity. l’Hôpital’s Rule states that:
d/dx [f(x) / g(x)] = d/dx [f\'(x) / g\'(x)]
In other words, l’Hôpital’s Rule says that when you need to find the limit of a division equation, you may find the derivative of the numerator and denominator seperately and place them into your equation. Do not use the quotient rule to find an overall derivative or this will not work.
