5.4 Solve Trigonometric Equations

1.Trigonometric equations can be solved in two ways:

• algebraically by hand
• graphically with technology

2. There are often multiple solutions. So, be sure to find all solutions that lie in the domain of interest.
3. Quadratic trigonometric ewuations can usually be solved by factoring.
