Trigonometry consists of learning how to use six different functions, or ratios, which show up in a surprisingly large number of places. Where do they come from? A good place to start is with some basic geometry. Remember similar triangles? If two triangles are similar, then they have equal angles and the ratio of their sides is the same.
To the Reader:
Welcome to trigonometry! If you are like most students, this is the last mathematics course that you will have to take before calculus, or in some cases, ever! One of the difficulties of trigonometry is that you will have to combine several of the skills that you have developed in previous classes, namely, geometry, algebra, and graphing. Furthermore, you will have to use both of these in algebraic problems and in word problems. This may sound intimidating, but it doesn’t have to be. Trigonometry can be challenging, but that doesn’t mean that you can’t handle it. Thanks to the book that you are about to use, you will be able to attack trigonometry and successfully conquer it.
One of the keys to doing well in trigonometry is memorizing. We recognize that many of you are not excited about the idea of memorizing the various ratios and formulas, but you will find that you will do much better, and have an easier time with trig, if you do. We will point out in the text what you need to memorize. We suggest that you do so!
Another key is to drill. This goes along with memorization. It is important to get comfortable with using the trig ratios in a variety of ways, and it will be much easier if you do all of the practice problems to reinforce the concepts. If you do so, you will find that trig isn’t so hard after all.
We have organized this book so that you can proceed from one topic of trig to another, or you can jump to the topics that you want to work on. The book is divided into 14 units, each of which will teach you what you need to know to do well in that topic. This is not designed to be an exhaustive treatise on trigonometry, nor is it designed to be a textbook. Rather, this book focuses on the essentials, and how to master the problems. We suggest that you read through each unit completely, do all of the exercises, and complete all of the practice problems. Each example and problem has a trigonometry, and after you have worked through a unit, you may want to refer to a textbook for further practice.
Trigonometry can be a fun and useful area of mathematics. After you have gone through this book, you will be able to handle the trig on your exams with ease, and you will be prepared for calculus. Are you ready? Then it’s time to Attack Trigonometry!
About the author
David S. Kahn teaches mathematics at Stony Brook University and is the author of “Cracking the AP Calculus AB & BC Exams.
This volume offers a succinct, exceptionally engaged survey of what secondary school and starting school students need to be aware to effectively tackle the geometry issues they will experience on tests. Thoroughly tried models and sound, tothepoint clarifications are introduced in an open structure and will give important help with overcoming this difficult subject.
As opposed to filling in as a message or composition, the book centers around the basics of geometry. Every one of the fourteen segments are coordinated in a way that permits perusers to progress successively or to skip around. The methodology energizes retention of proportions and recipes, and the training issues offer sufficient chances to become OK with applying the trig proportions to different settings.
