Trigonometry

Building on previously acquired math skills that involved different formulas for finding the area of shapes, this course intensifies the focus into more sophisticated applications. In Area and Triangle Laws, you will learn how to solve more complex area problems. By using the Law of Sines or Heron's Formula, you will practice Finding the Area of an SSS Triangle and Solving for a Side with the Law of Sines. You will also learn how the Law of Sines can help discover Ambiguous Triangle Identities.
