Trigonometry Collected Resources
A resource covering all aspects of Trigonometry. This collection was my senior project for my degree in Mathematics. I have collected resources that were already out there, a lot of Tim Brezsinski's Trig modules, some from the GeoGebra Content team, and a few others that were exceptional. Then with my faculty advisor, I set out to create some content that I felt was lacking. This resource can be used to learn Trig, teach Trig, or just freshen up or expand your knowledge in the area. This book is a work in progress, and will be added to as I find and/or create new quality stuff.
