Rigor: You will learn how to solve trigonometric equations by using algebraic techniques and by using basic trigonometric identities. Relevance: You will be able to use trigonometric identities to solve real world problems.

4
5-3 Solving Trigonometric Equations

5
Example 1: Solve Trigonometric Equation for all values of x. The period of tangent is , so we need to find solutions on the interval [0, ). So the general form for all values of x is

6
Example 2: Solve Trigonometric Equation for all values of x. The period of sine is 2 , so we need to find solutions on the interval [0, 2 ). So the general form for all values of x is
