Trigonometry Essentials Practice Workbook with Answers

.

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.

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.
