Trigonometry: A Complete Introduction: The Easy Way to Learn Trig

My husband said the Trigonometry book is excellent overall - very helpful indeed and arrived very promptly. Thank you.

Good price, like the maths, physics versions, very helpful.

The Book was spot on for the purpose I purchased it for. My grandson is entering grade 9 where Trig starts to expand its importance, This book is there to compliment his school curriculum and will expand his knowledge base. Looking through, I'm impressed

Lots of useful information

well explained, could do with more worked examples

As before brushing up, good book

This could have been a good book. The biggest issue I have is that the examples are too vague and could give some more. The exercises comprise of a number of questions with the answers in the back. If you fail to get an answer there is no way to find out how to resolve it. To me not very informative and not very good at teaching the subject. Shame, because the potential was there

ok

Introduction progressive à la trigonométrie, bon ouvrage.

not bad

Justo ahora empecé y ya me encanta, no es difícil y bastante intuitivo.

Great organization and pace to the book. Explanations are generally effective. There are some questions with phrasing susceptible to more than one interpretation, completely unclear, or requiring assumptions, such as referring to sin and cos of two angles but not being told explicitly they are adjacent angles. Overall it's still a great book.

Good book. Covers the fundamental concepts very well.
