I decided to implement a tau-based approach to trigonometry out of my own personal curiosity. I did not do a formal study so the observations below should be taken as informal, preliminary, and tentative. If other educators are using tau in a trigonometry context, I would be interested in hearing about your experiences and add your thoughts and observations to this website. My email is at the bottom of the page.
