• 5.1: Graphing the Trigonometric Functions
The trigonometric functions can be graphed just like any other function, as we will now show. In the graphs we will always use radians for the angle measure.
• 5.2: Properties of Graphs of Trigonometric Functions
We saw in Section 5.1 how the graphs of the trigonometric functions repeat every 2π radians. In this section we will discuss this and other properties of graphs, especially for the sinusoidal functions (sine and cosine).
• 5.3: Inverse Trigonometric Functions
We have briefly mentioned the inverse trigonometric functions before, but we will now define those inverse functions and determine their graphs.
• 5.E: Graphing and Inverse Functions (Exercises)
These are homework exercises to accompany Corral's "Elementary Trigonometry" Textmap. This is a text on elementary trigonometry, designed for students who have completed courses in high-school algebra and geometry. Though designed for college students, it could also be used in high schools. The traditional topics are covered, but a more geometrical approach is taken than usual. Also, some numerical methods (e.g. the secant method for solving trigonometric equations) are discussed.
