Project Mathematics! Sines & Cosines, Part II VHS 30 minutes/1993 Grades 9-12
Focuses on the use of sines and cosines in trigonometry, with special emphasis on the laws of both cosines and sines. They enable us to fin all parts of a triangle if three parts are known and at least one of them is a side. Applications are described in astronomy, navigation, and surveying by triangulation. One of the major triumphs of surveying by triangulation is the survey of India, which took more than a century to complete. The program describes how the survey was done and how the height of Mt. Everest was determined. The program also outlines a brief history of surveying instruments, from the dioptra of ancient times to orbiting satellites of modern times.
