Fall 2014

2. Dealing with Multiple Angles
Solve the equation to isolate the trig function
Solve the equation for (exactly) what is inside the trig function (the angle you see)
Solve the resulting equations for the variable.
Determine the period of the function(s) in the problem.
Remember, period is how long it takes the function to repeat.
Use the period to find the rest of the answers that are required.

3. Example 1
Solve the equation on the interval [0, 2π).

4. Example 2
Solve the equation.

5. Example 3
