# Algebra Introduction

### Topics

We mentioned graphs a little earlier, but we’ll do a lot more than mention them in this guide. In fact, we're going to be getting up close and personal with graphs of all sorts of different shapes and sizes. You’ll learn several different methods for plotting graphs, and you’ll be introduced to graphs with functions that have varied and unique shapes. Like this:

or this:

or even this:

Okay, maybe not that last one. Relax, we're kidding. Gawrsh.

We’ll go over **sines**, **cosines**, and **tangents**, which are the ratios of a triangle's sides. You’ll be able to use your calculator to graph these functions, which is awesomesauce. Unless you find that word obnoxious, in which case we can just go with awesome.

The really heavy-duty graphing won't join the party until we get to trigonometry and calculus, but algebra will at least help you get your feet wet. In fact, you might want to bring along a spare pair of dry socks.
