In the previous chapter, the trigonometric functions were introduced as ratios of sides of a right triangle, and related to points on a circle. We noticed how the x and y values of the points did not change with repeated revolutions around the circle by finding coterminal angles. In this chapter, we will take a closer look at the important characteristics and applications of these types of functions, and begin solving equations involving them.
- 6.2: Graphs of the Other Trig Functions
- In this section, we will explore the graphs of the other four trigonometric functions. We’ll begin with the tangent function.
