About this Book
Graphing calculators are a useful tool for students, teachers, SAT test-takers, professionals, and just about anyone who needs to work with numbers and graphs. You can use a graphing calculator to help solve math and science problems or to check your work, to draw graphs and manipulate statistics, and even to write programs. But all this power can make your graphing calculator an intimidating device. With all the features it offers, you might have difficulty figuring out where to start. And that’s where this book comes in. It focuses primarily on the TI-83 Plus and TI-84 Plus-family calculators but also can help you with any TI-83, TI-83.fr, TI-82, or TI-82 Stats.fr calculator. In the coming chapters, you’ll see almost everything your calculator can do, from the simplest arithmetic to complex graphing, statistics, calculus, and programming.
