Chapter 3 – Trig Formulas and Inverse Functions
Combining Trig and Inverse Trig Functions – Part I covers several examples of how these functions can be combined. The emphasis is on developing the notation and understanding at each step whether the object in question is an angle or a number. Attention is given to the domain and range of the functions. These issues are important for lessons in solving triangles using The Law of Sines and The Law of Cosines. Example 2 in the video is a repeat from Pythagorean Theorem – Trig Version.
