WebMar 24, 2024 · Circular Functions. The functions describing the horizontal and vertical positions of a point on a circle as a function of angle ( cosine and sine) and those functions derived from them: Circular functions are also called trigonometric functions, and the study of circular functions is called trigonometry . WebValues of Quadrantal Angles. When an angle lies along an axis, the values of the trigonometric functions are either 0, 1, -1, or undefined. When the value of a trigonometric function is undefined, it means that the ratio for that given function involved division by zero. Below is a table with the values of the functions for quadrantal angles. WebThis bundle includes everything you need to teach your students about evaluating inverse trigonometric functions.
