Learn or Review Trigonometry: Essential Skills (Step-by-Step Math Tutorials)

I think I have pretty much all of chris’s books now. He is an excellent instructor and pretty much the reason I’m passing my hnc. Many thanks for the excellent resources!!!

It's been a while since I HAD to study trigonometry on a mathematics course. Coming back to the subject voluntarily meant I was under no pressure, so I could take my time. McMullen's book has made the experience enjoyable. My main disappointment was that he didn't introduce the "arc-" inverse trigonometric functions. They avoid the confusion that results from using the same symbol (the superscript [–1]) for inverse functions and for multiplicative reciprocal. Otherwise, I'd just like to thank Chris for a good book.

The content is well laid out

I am not a math person, but am a visual person. I purchased this because it is an excellent example (I looked at a few) I liked of how to utilize the Kindle Book software. On his blog (...), the writer brilliantly spells out details of how to optimize Kindle's software features, and this book is the illustrated outcome. So glad to have found this practical, perfect example of design and layout... plus I can learn a few new angles!

Really easy to understand and explain!

A good, concise summary of trig and geometry concepts.
