Variables are used throughout Algebra, Geometry, and Calculus. They are the basic building blocks. Variables are therefore very important to understand.

A variable is a symbol, such as x, that is used to describe an unknown number. In functions variables often represent not one number, but many different numbers. Understanding variables is essential for you to understanding problems that will need to be graphed.

  1. What Are Periodic Trigonometric Functions?

Periodic Functions: Sine and cosine are periodic functions, which means that sine and cosine graphs repeat themselves in patterns. You can graph sine and cosine functions by understanding their period and amplitude.

How Do You Graph Rational Functions, n=m?

Rational Function Graphs: There are different characteristics to look for when creating rational function graphs. With rational function graphs, we can find a horizontal asymptote where the degree of the numerator function is equal to the degree of denominator function. There are other techniques for drawing rational function graphs when the degree of the numerator is less than, or greater than, that of the denominator.
