Topics:
• Solving the basic trig equations: 
The methods are developed in these examples:
Example 20.1 for
Example 20.4 for
Example 20.7 for
Examples 20.3, 20.6, and 20.9 use the developed methods to solve other basic trig equations.
See the useful Summary just before Example 20.10 on p. 275
• Solving other types of trig equations by reducing them to one or more basic equations. (Examples 20.10 and 20.11)
Homework:
• Study the examples which were used to develop the methods for solving the basic trig equations. Make sure that you understand the reasoning behind them.
• Review the other examples discussed in class.
• Do the assigned problems from Session 20.
• Make sure you do the WeBWorK (assigned last time).
• No Warm-Up this time.
• Spend a few minutes every day reviewing the basics of trigonometry, and reviewing the properties of logarithms. I have posted a very short WeBWorK assignment “LogReview1” to help in this review. It is optional and will count as extra credit in your WeBWorK score. I will post other short review assignments throughout the rest of the semester.
