- 2.1: Graphs of the Trigonometric Functions
- In this section, we return to our discussion of the circular (trigonometric) functions as functions of real numbers.. As usual, we begin our study with the functions f(t)=cos(t) and g(t)=sin(t).
- 2.2: The Inverse Trigonometric Functions
- In this section we concern ourselves with finding inverses of the (circular) trigonometric functions. Our immediate problem is that, owing to their periodic nature, none of the six circular functions is one-to-one. To remedy this, we restrict the domains of the circular functions in the same way we restricted the domain of the quadratic function previously.
