So far in my plan to make a trig program bundle, I have a display for the unit circle, Trig function generation based on manual input of angles, a trig table of functions on the main angles (30/45° multiples), finding the reference angle, and deg/rad conversions. Let me know if any useful trig programs I could find or make! Thanks to all the people who have helped me out so far with this as well!
I have a Unit Circle program for the TI-84 Plus CSE or the CE, found at It gives you the exact sine, cosine, and tangent values for every 15 degrees. I plan on updating it soon, so it will have cosecant, secant, and cotangent. Hope that's helpful.
