Good morning everyone,
I have written a free math textbook, and I'd appreciate some feedback on it. It's about the basics of Trigonometry, including sine, cosine, tangent, radians, the unit circle, a bit on identities, and the Law of Sines, Cosines, and Tangents. I wrote it in a rigorous manner, attempting to be very formal, avoid gimmicks, avoid mere recipes, and share much of the theory and intuition behind these fundamental concepts in Trig.
I wrote the book for 9th/10th grade Geometry students. I had a few goals with this text: First, I had a good class, and I wanted to give them a reasonable. Second, Trig is sorely lacking in our curriculum, and I found that students were completely unprepared for Trig in later classes, and as a result, many struggled in subsequent classes, particularly in Pre-Calculus. Finally, I wanted to give my students a formal math experience, in hopes that they might find it enjoyable - or, at least, more enjoyable than the contemporary math books they've used up to this point.
As you can see, this is the 1st Edition, and I want to make some improvements for the 2nd edition.
Finally, this text is completely free. You may copy, print, share, etc. this text as you desire.
Thank you for your time and your feedback.
