Inverse Trigonometric Functions

Curated and Reviewed by Lesson Planet

Build on the understanding of finding angles using trigonometric ratios. Pupils develop the definitions of inverse trigonometric functions by restricting their domains in the 13th lesson of a 16-part series. They use inverse functional notation to denote the inverses. Class members move on to use inverse functions to solve trigonometric problems.
