In the last two chapters we have used basic definitions and relationships to simplify trigonometric expressions and solve trigonometric equations. In this chapter we will look at more complex relationships. By conducting a deeper study of trigonometric identities we can learn to simplify complicated expressions, allowing us to solve more interesting applications.
- 7.1: Solving Trigonometric Equations with Identities
- In the last chapter, we solved basic trigonometric equations. In this section, we explore the techniques needed to solve more complicated trig equations.
