Starr Books offers Part 3 (of 4) of Quantum Scientific Pre-Calculus covers trigonometry. Unit 1 lays out the basics of trigonometry, including angle measures, the unit circle, the trigonometric functions, and solving right triangles. Unit 2 presents the graphs of the trigonometric functions as well as a look at some applications of the functions. In Unit 3, the focus is on trigonometric identities. The Law of Sines and the Law of Cosines are also described along with applications of these laws. (Please see thumbnails for the full table of contents and some sample pages.)
Each part of this pre-calculus series is broken into three units with 15 lessons each for a total of 45 lessons per part. The four books in the series offer 180 lessons for a full year’s study. Lessons include examples and practice exercises. (Be sure to download the free Exercise Answer Key for each part of the series.) The individual lessons can be used as study guides, test preparation materials, and review of previously-learned content. The exercise sets can also be used as worksheet, quizzes, and tests.
