Here a complete, easy-to-grasp course in trigonometry that takes
the form of a fantasy novel. The King of Carmorra and his subjects
have many practical problems to solve, and their answers can be
found by applying principles of trigonometry. Readers follow along
and learn to solve many different problems that can be reduced to
triangular diagrams. They learn the laws of sine and cosine,
trigonometric functions and inverse functions, waves, conic
sections, polynomial approximation, and much more. The book is
filled with instructive exercises and their solutions, plus illustrative
drawings, graphs, and diagrams. This new edition contains updated
coverage on using graphing calculators and computer
spreadsheets for solving trigonometric problems.
