Chapter 8: Further Applications of Trigonometry

In this chapter, we will explore additional applications of trigonometry.  We will begin with an extension of the right triangle trigonometry we explored in Chapter 5 to situations involving non-right triangles.  We will explore the polar coordinate system and parametric equations as new ways of describing curves in the plane.  In the process, we will introduce vectors and an alternative way of writing complex numbers, two important mathematical tools we use when analyzing and modeling the world around us.
