Section 6.3 – Solving Trigonometric Equations 1 Section 6.3 Solving Trigonometric Equations An equation that contains a trigonometric expression is called a trigonometric equation . As we know trigonometric functions repeat their behavior. What if we wanted answers to questions like: “When will the moon look exactly like it did last night at 9:30pm?” and “When will my breathing be exactly as it is right now?”. The questions to these models can be answered by solving trigonometric equations. Example 1: Find all solutions in the interval [ 29 π 2 , 0 of the equation 1 ) tan( - = x . Example 2: Find all solutions of the equation 1 ) tan( - = x . Example 3: Solve the equation in the interval
