Featuring progressive problem sets and a detailed answer key, it’s ideal for learners aiming to deepen understanding and accelerate their math studies. ## Description AUTHOR : Chris McMullen earned his Ph.D. in physics from Oklahoma State University and currently teaches physics at Northwestern State University of Louisiana. He developed the Improve Your Math Fluency series of workbooks to help students become more fluent in basic math skills. WHAT TO EXPECT : This is a workbook designed to offer plenty of practice with essential skills. It is not a textbook designed to teach trigonometry, but a workbook designed to supplement a student’s instruction in trigonometry. Examples and a brief description of the concepts are included to serve as a quick refresher and a guide. If you need more instruction, you should use this workbook in combination with a textbook. The last chapter involves applications of trig identities, which is a challenging topic that will mostly interest more advanced students. A few chapters are intended to help students memorize the trig functions of common angles like 30, 150, or 315 degrees, which will be especially useful for students who may take exams without a calculator (that’s the case with the MCAT and many math and science courses). There may be more practice than many students need, which is much better than having too little practice. Any extra pages may be helpful for teachers or parents with multiple children. DESCRIPTION : This Trigonometry Essentials Practice Workbook with Answers provides ample practice for developing fluency in very fundamental trigonometry skills. Every problem can be answered without a calculator, which is very helpful for students who aren’t allowed to use a calculator. This is the case in some trig and physics courses, as well as some standardized exams (like the MCAT). CONTENTS : This workbook is conveniently divided up into 11 chapters so that students can focus on one trigonometry skill at a time. Skills include the following: converting between degrees and radians; expressing sine, cosine, tangent, secant, cosecant, and cotangent as fractions by looking at right triangles; solving for unknown sides and angles in 45°-45°-90° and 30°-60°-90° right triangles; determining the sine, cosine, tangent, secant, cosecant, and cotangent of multiples of 30° and 45° up to 360° (working with both degrees and radians); practice finding the reference angle for angles in Quadrants II, III, and IV; finding the inverse trig functions; applying the law of sines and the law of cosines to solve for unknown sides and angles in acute and obtuse triangles; solving problems with trig identities (like the angle sum and difference formulas); and solving algebraic equations that feature basic trig functions. EXAMPLES : Each section begins with a few pages of instructions for how to solve the problems followed by some examples. These examples should serve as a useful guide until students are able to solve the problems independently. ANSWERS : Answers to exercises are tabulated at the back of the book. This helps students develop confidence and ensures that students practice correct techniques, rather than practice making mistakes. PHOTOCOPIES : The copyright notice permits parents/teachers who purchase one copy or borrow one copy from a library to make photocopies for their own children/students only. This is very convenient if you have multiple children/students or if a child/student needs additional practice. INTRODUCTION : An introduction describes how parents and teachers can help students make the most of this workbook. Students are encouraged to time and score each page. In this way, they can try to have fun improving on their records, which can help lend them confidence in their math skills. Review: EXCELLENT WORKBOOK (if you overlook the occasional typo) - A good quality workbook. Well defined processes, with graduating order of problems such that the reader is well prepared for the next step. If learning from scratch, students will realize much greater success if making sure they clearly understand the each chapter before moving on. This understanding of trig functions given here makes memorization obsolete, as you understand the logic behind each determination. I am so glad to save this time of memorization and just have a clarity of understanding the unit circle, signs of each sin/cos/tan per quadrant, without wasting any time. Even the typos are so few that when you find them, its rather apparent, and a fun surprise. P14 answer key for problem 11 is incorrect, P 32 has a typo in the additional terms csc, sec, cot p 96 example 2 defines an angle of 210º in quadrant 2, which is actually in quadrant 3 and will change the sign of the answer There may be other typos, but that's all I found. It would be nice if the publisher listed on a website so purchasers can correct them before attempting to learn trigonometry from scratch. Its nice for all navigators to receive updates whenever a buoy or an island is incorrectly described on a chart, and so too would this greatly serve the student navigating trigonometry. Overall a good learning book, just shy of greatness. Has helped me a ton preparing to test out of trig into precalculus and save a whole semester for crucial prerequisites. Thank you author! If anyone knows of any good books for calculus and precalculus, let me know. Review: Necessity for Trig Students - Perfect condition, bought this to help me prepare for trig next semester. Just received it today and I already finished 2 chapters. Very straightforward and helpful. ## Features - Used Book in Good Condition ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #69,035 in Books ( See Top 100 in Books ) #6 in Trigonometry (Books) #16 in Children's Advanced Math Books #20 in Algebra & Trigonometry | | Customer Reviews | 4.6 out of 5 stars 921 Reviews | ## Images ![Trigonometry Essentials Practice Workbook with Answers: Master Basic Trig Skills: Improve Your Math Fluency Series (Volume 16) - Image 1](https://m.media-amazon.com/images/I/61xQEe1iZwL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ EXCELLENT WORKBOOK (if you overlook the occasional typo) *by D***E on June 5, 2017* A good quality workbook.
