This chapter explores trigonometric ratios in the context of problem solving in right triangles, non-right triangles and the unit circle. Radian measure and connections to area of triangles are also explored.
In this chapter, you will learn about the sine, cosine, tangent, secant, cosecant, and cotangent of angles in degrees and radians. You will be introduced to Polar coordinates, as well as the Laws of Sines and Cosines. Several real-life applications will be explored.
