Lesson: 4.7 Inverse Trig Functions
Goal: Use inverse trig functions to find angle measures DOD
Trig Functions take an angle as an input and output a ratio.
Inverse Trig Functions take a ratio as an input and output an angle measure.
In general, inverse functions flip the domain and range.
Specifically, for inverse trig functions, you need to restrict the domain so that we still
have a function (and not a relation). Ch_4 Page 1 Domain:
