Moving into "The Joy of Recreational Mathematics", readers are treated to mind-bending puzzles, numerical curiosities, and clever logic games that make math irresistibly fun. Finally, the spotlight shifts to Srinivasa Ramanujan, whose life and discoveries showcase the limitless possibilities of human imagination when intertwined with numbers. His work, often bordering on the mystical, is brought to life through clear explanations and historical context.This book isn’t just for mathematicians—it's for anyone who has ever wondered about the magic behind numbers. Through an engaging blend of theory, application, and biography, it invites readers to see math not as a subject to fear, but a realm to explore with wonder and joy.⭐⭐⭐⭐⭐ “An exceptional book that bridges mathematical elegance and human genius. Ramanujan's story is beautifully interwoven with exciting puzzles and insights. A must-read for anyone looking to rekindle their love for numbers.”⭐⭐⭐⭐ “A wonderfully written and enjoyable dive into recreational math and number theory. Some concepts require a bit of patience, but the journey is absolutely worth it. The Ramanujan section was particularly inspiring.”⭐⭐⭐⭐ “Creative, insightful, and educational. The authors have made math feel like an adventure. A bit dense in some sections, but still an engaging read for enthusiasts and curious minds alike.”⭐⭐⭐ “Interesting content, especially the parts on Ramanujan. However, the flow between the three sections could be better structured. It feels like three books in one rather than a seamless narrative. Still enjoyable for fans of math.”⭐⭐⭐⭐⭐ “I was hooked from the first chapter! The puzzles were playful and intriguing, and the tribute to Ramanujan was both moving and intellectually satisfying.

A #1 SUNDAY TIMES BESTSELLERExplore the life-changing magic of trigonometry with Matt Parker, stand-up mathematician and No. 1 bestselling author of Humble PiWhy can no two people ever see the same rainbow? What happens when you pull a pop song apart into pure sine waves and play it back on a piano? Why does the wake behind a duck always form an angle of exactly 39 degrees? And what did mathematicians have to do with the great pig stampede of 2012? The answer to each of these questions can be found in the triangle.In Love Triangle, stand-up comedian, ex-maths teacher and Sunday Times number one bestselling author Matt Parker is on a mission to prove why we should all show a lot more love for triangles, along with the useful trigonometry and geometry they enable. To make his point, he uses triangles to create his own digital avatar, survive a harrowing motorcycle ride, cut a sandwich into three equal parts, and measure tall buildings while wearing silly shoes. But soon these hare-brained experiments begin to reveal a genuinely important truth: triangles are the hidden pattern beneath the surface of the contemporary world, used in everything from GPS to CGI via Spotify streaming, the play button and your best mate’s triangle tattoo.Join Matt Parker as he demonstrates why there’s more to triangles than Pythagoras and SOHCAHTOA. Triangles are everything and everything is triangles. Read more

This trigonometry workbook focuses on trig identities. The majority of the exercises let you derive a variety of trig identities by following similar examples. If you get stuck, helpful hints in the back of the book help walk you through the solution. Other exercises include applications, such as how to find the tangent of 15 degrees without a calculator or how to apply trig identities to solve equations. This book also serves as a handy list of numerous trig identities organized by topic. The answer to every problem can be found at the back of the book. The author, Chris McMullen, Ph.D., has over twenty years of experience teaching math skills to physics students. He prepared this workbook of the Improve Your Math Fluency series to share his knowledge of trig identities. Read more

EDITIONS: Originally published as a paperback workbook, this print replica digital format is designed for value pricing (compared to the print edition) and the convenience of electronic storage. Pinch-and-zoom allow for close-up reading. Problems can be worked out on scratch paper. Also available in paperback.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. Read more
