Inverse Functions and Trigonometric Equations

open access: closed, 2001
Let us recall the definition of a function. If we have two sets A and B, a function from set A to set B is a correspondence between elements of A and elements of B such that 1 Each element of A corresponds to some element of B, and 2 No element of A corresponds to more than one element of B.

Conceptions of Angles, Trigonometric Functions, and Inverse Trigonometric Functions in College Textbooks

International Journal of Research in Undergraduate Mathematics Education, 2016
Using expository text and examples available in 10 college textbooks we identify two conceptions of angles, trigonometric functions, and inverse trigonometric functions that rely on either a static or a dynamic definition of angle. Although the textbooks favor a conception of trigonometric functions that is based on a dynamic conception of angle, they ...
