Warm-Up 10/28 1. D

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.

5-3 Solving Trigonometric Equations

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

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

Example 3: Find all solutions for the equation on[0, 2  ).

Example 5: Find all solutions for the equation on[0, 2  ).

Example 6: Find all solutions for the equation on[0, 2  ).
