Chapter 8: Parametric Equations and Trigonometry

In this chapter:

  • Use a third variable to write parametric equations that separately define x and y
  • Simulate objects in motion with parametric equations
  • Convert between parametric equations and equations that use only x and y
  • Review the trigonometric ratios—sine, cosine, and tangent
  • Use the trigonometric ratios and their inverses to solve application problems
