Students need the best teacher, so you need examples, because examples are the best teacher. All the examples in this book are fully worked, and help you do math better. And this book is about a math idea called trigonometry. Why trigonometry though? That's primarily because we often get to work with angles not only doing geometry but doing algebra, too. Doing high school math or college math, we can hardly avoid or stay away from algebra. And doing geometry, too, we often get to do algebra on expressions with angles. And doing such algebra, we can say that we do trig-algebra. And next, we need to do trigonometry if we have to work with vectors and many other objects that have to do with angles. Working with such objects, we often need to find objects called components, which have directions or angles. Finding such components, we want to use some tools in trigonometry. And the tools are called trigonometric-ratios, often just called trig-ratios, for short. So doing trigonometry, we get to use trig-ratios called sines, cosines, etc., together with a bit bigger tools called trig-identities, and some rules or formulas. So in this book, you get to know what those tools are and what they are about. That is to say that you will get to know how those tools work, what you can do with them, and how to work with them. Specifically, you will get to learn, for instance, how the trig-ratio called the sine is made, what it is about, and how to use it. More specifically, you will see why you have to multiply by the sine, and what you get multiplying by it. And of course, you will get to learn those important tools called trig-identities and the formulas called the Sine Rule and the Cosine Rule. Besides, you will get to see and will be familiar with some special tools called trig-functions. And you will get them all through examples, that is, those tools will get explained with examples fully worked and detailed. Also, following steps to the solution in each example, you will be more familiar with the tools and the math ideas. And you will get to strengthen your skill of algebra. So doing problems as well as learning ideas in math, you can do better and faster so that your math can run not only properly but fast enough, too. And of course, I can go more of blah-blah-blah, and anyway, end up with saying that this book is the best ever, and is so great to buy. So what is good, and how good is it? What author in the world is saying that his or her own book is just so-so or bad? So you may want to take a look at the actual book, and read some pages in it. Where then, is the book? You can look at some sample, which is a good amount of excerpt, and you can get it downloaded using the link as follows: https://www.createspace.com/Preview/1099145 The link above belongs to CreateSpace, which is part of the Amazon group of companies. So no worry about getting something bad. May your math run very well. Seong R. Kim B.S. Math. Michigan Tech. Univ. M.S. Math. Rensselaer Polytechnic Institute
