This book is for users of the TI-84 Plus graphing calculator family. It focuses on the most relevant functions for high school and college. It starts off with the basics of the calculator like accessing all the different menus, editing equations and how to graph functions. Furthermore, it explains all the settings of the calculator and gives you recommendations about what you should choose to get the most out of your calculator. The book continues to teach you how to analyze your functions like finding zeros, minimums, maximums and intersections, and how to calculate integrals and derivatives. Additionally, it gives you all the information you need to work with matrices and lists. The last chapter focuses on statistics and probability. It teaches you the difference between permutations and combinations, and shows you how to perform one and two-variable statistical data analyses or regressions. Buy this book if: you are a high school student; you are in college; you want to learn how to use your TI-84 Plus quickly and easily; you don't want to read a 300+ page book about how to write programs on your calculator. Why is it so easy to understand the TI-84 with this book? Short and easy to understand explanations of each topic. I don't spend a whole page talking about how to use one key. I've kept it short and concise. Images of the real calculator keys between the text. So, for instance, when I say "Press [GRAPH] and use the arrow keys []..." the book shows the real buttons. This makes it super easy to follow the steps on your calculator. Beside the flowing text, I found it more useful to provide you with some simple keystroke sequences for some calculations. Look at it, and you instantly know how to do it - it's that simple! Lots of screenshots to give you real examples. This book is your perfect buddy for these calculator models: TI-84 TI-84 Plus TI-84 Plus Silver Edition TI-83 Plus These calculators have a black and white display. If you have a newer calculator with a color display like the TI-84 Plus C or TI-84 Plus CE, this book is not for you. However, I have written another book just for the newer calculators. I decided to write two books so I can show you exactly the right screenshots and keys that apply to the individual calculator model you have (most other books just use a similar calculator to make one book for all models). About the Author My name is Marco and I graduated from high school in 2013. I was quite good at mathematics and often helped my classmates to understand it better - especially how to use their calculators. It just has been a few years since I was using the TI-84 Plus myself. Therefore, I know how students think and what they need. I know they don't need a book with more than 300 pages to understand a graphing calculator. While writing my book, I kept in mind that it should be simple to understand and as short as possible so as not to confuse students with too much background information. Besides that, I remembered that even if I previously knew how something worked, I often forgot the keystroke to do it. So I created simple step-by-step keystroke sequences for most commands and calculations, which makes it so easy to look them up and instantly be able to do it - with no need to read through a long text. After I graduated, I developed an app that teaches how to use the TI-84 Plus. My app is helping a lot of students use their calculators and is frequently ranked in the Top 10 Education USA on iOS and Android. Visit http://www.ti84-calculator.com/manual for more information.
