10.4. MORE TRIGONOMETRIC EQUATIONS 467 sin −1 (0) = 0 ◦ , 180 ◦ cos −1 (0) = 90 ◦ , 270 ◦ tan −1 (0) = 0 ◦ , 180 ◦ Let’s look at how this is used in solving an equation: Example 1 Solve the given equation for 0 ◦ ≤ x
468 CHAPTER 10. TRIGONOMETRIC IDENTITIES AND EQUATIONS Another approach to solving trigonometric equations involves using Pythagorean Identities to make a substitution that so that the equation can be simply solved by the quadratic formula. Here’s an example: Example 2 Solve the given equation for 0 ◦ ≤ x
