# Introduction

Welcome to the SageMath Calculus Tutorial! From initial concepts to increasingly complex techniques and applications, this tutorial is meant to accompany a high school- or college-level beginning calculus course. You'll learn how to interact with the incredibly robust, yet free and open-source, SageMath Computer Algebra System.

No previous experience with SageMath or calculus is necessary, though you will need to either download SageMath or work online at CoCalc in order to participate actively in the following lessons.

In particular, there are prepared versions of these lessons as executable worksheets right on CoCalc! First, create an account and a project. Then you can get a copy of the files from here!

If you know little or nothing about writing code - don't despair! Below most code snippets you will find a blue "Toggle Explanation" link, which when clicked will explain line-by-line how the code works. If you would first like to brush up on some pre-calculus and trigonometry concepts, this review may be of help.

If the tutorial's text is difficult to read, try zooming in or out using your browser's shortcuts. In Internet Explorer 7 and Firefox 1.0-3.x, pressing CTRL then + will zoom in, while pressing CTRL then - will zoom out. If your browser does not include such a feature, use the + and - keys to increase or decrease the font size from any page in the tutorial.
