Trigonometry Essentials Practice Workbook with Answers: Master Basic Trig Skills: Improve Your Math Fluency Series (Volume 16)

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.

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.

Great book, easy to understand, and good price.

The book explains things pretty well for the most part. There are a bit too many problems in the beginning chapters, but I just skipped ahead after I got a several pages without issues. I enjoyed the theories, but I was disappointed in chapter 10’s crazy over the top jamming in a bunch of identities at once. Some people are probably okay with it, but I need practice with each theory and then combine them. It has a feeling of “Step One” -> “Step Two” -> “Step Ten”. Definitely some laziness in jamming it all in at the end like they were running out of pages and needed to finish. Overall, a good book. But, you will need more than just this book to master Trig.

Efficiently written and easy to grasp.

Even if you were never very good at math, if you get a workbook to help your child learn math, I suggest that you let your child try to explain the math in the workbook to you and that you try to understand what your child tells you, because many people who have trouble with math learn better when they try to put it into their own words, or if they can't find the right words, maybe asking them questions will help both of you figure it out. And learning to ask questions about math will help students ask the teacher questions if the teacher doesn't explain well enough!

Like the explanation and examples at the beginning of each chapter. There is an answer key at the end of the book but if you get one wrong you may want to go back to the example to see why because the key only shows the final answer. I like that there are extra blank pages at the back for notes. There is enough blank space throughout the book for notes and to do the problems on each page. The paper was good, I used pentel ink pen without bleed through and regular pencil and pentel pencil both wrote well on the pages with some dents showing on the next page. The examples had a nice variety and the problems for a section were more advanced as you worked through. Each section has plenty of problems for a week.

The content seems good but not all of it is legible. The outside edges of the pages are cut off, gradually worsening towards the end of the book. No customer service seems to be available for this item. Kind of a rip-off.

Bonjour, L'auteur de ce livre est un génie pédagogique...MAIS IL EST AMERICAIN... et c'est pour des gens comme lui, comme fut aussi Richard Feynman et des centaines d'autres que les américains rafleront définitivement la quasi totalité des prix Nobel de toutes sciences. Rien à voir avec nos prétentieux, théoriques incompréhensibles des élèves, maîtres français trop diplômés et loin du peuple "moyen"...! Francis Benoit G.

In retirement I decided to revisit Maths bur didn’t realise how out of touch I was. One are was trigonometry. This book I found so easy to read, and right to the point. My advice: don’t skip the exercises! You may think you get it but they really put you to the test. I found the introduction to each section was so easy to follow, and (provided to read it properly) really got you to where you needed to be. Highly recommend this to anybody

Très complet pour éviser des notions oublées

Muito útil e bem explicado coisas que não lembramos ou aprendemos. Recomendo para quem precisa voltar a estudar ou iniciantes.

Covers a lot. Good practice pages. I really needed a good explanation of half-angle, double-angle, etc. type formulas. Good explanations are hard to find on the Internet (or at school, sadly). The last couple chapters were really good in this regard. I'd highly recommend.
