Most impressive study guide

I've reviewed most of the trigonometry study guides and nothing comes close to Trigonica. I was able to understand the basics of trigonometry the first time reading the Trigonica study guide without confusion! Thank you so much for making this priceless guide available to the public for free. You are a fantastic teacher.
