This chapter allows students to use their graphing calculators to determine the relationship between Heron’s formula and the basic area formula. Students are also tasked with deriving and using the Law of Sines.
This chapter develops a student’s knowledge of polar coordinates by graphically and algebraically finding slopes on a polar graph. Additionally, students practice representing complex numbers in the complex plane as points and vectors.
CK-12’s Texas Instruments Trigonometry Teacher’s Edition Flexbook is a helpful companion to a trigonometry course, providing students with more ways to understand basic trigonometric concepts through supplementary exercises and explanations.
