TI-Nspire Trig Formulas Document

The first formula sheet document I am releasing for the TI-Nspire is one for trigonometry formulas. There are quite a few trig identities for students to memorize, so I hope this will serve as a good reference for you. This file will work for any up-to-date version of the TI-Nspire, including CAS or non-CAS, CX or grayscale. The table of contents follows below.
