In this section, you will learn to: • Use standard algebraic techniques to solve trigonometric equations • Solve trigonometric equations of quadratic type • Solve trigonometric equations involving multiple angles • Use inverse trigonometric functions to solve trigonometric equations
Two basic techniques for solving trigonometric equations are factoring and applying known identities. a) Rewrite the equation with a single trigonometric function. b) Remember only to factor after you have set the equation equal to zero.
