Here's 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.

A very good and unique book written like a fantasy story.It is set in the fictional kingdom of Camorra.It being written like a fantasy story
I guess might be of particular help to some people for understanding it.The plot is basically about acquaintances of the king who after stopping a near flood realize how helpful triangles are and find out about the nature of them.Eventually they also meet a man named Trigonometris who helps them with "the Gremlin's" challenge to build a bridge in time.They complete the challenge & also prevent another flooding accident.Other people learn about the uses of trigonometry and they help their friend (a giant named Pal) make a carrier pigeon system.The 1st 11 chapters make up the main story.There are an extra 4 chapters on complex numbers,coordinate rotation,spherical trigonometry and the polynomial approximation for sin x and cos x. This is an excellent book for anyone who would not only like to learn trigonometry but also know how is it that concepts in trigonometry originate,are derived and developed.The questions can be answered by anyone who is knowlegdable about trigangles from late elementary school to a high schoool student who has taken advanced functions.There are a variety of topics such as radians,inverse trigonometry, trigonometric identities,the periodic function(there is a note about Fouriers theorem at the end of that chapter),polar co-ordinates and there are questions which mix in physics concepts.There are also questions in which you have to derive a formula on your own (which I personally find difficult)or prove a formula.
A note about a few of the questions:they are suppose to be done as programs in a now outdated BASIC programming language.Answers to questions and an appendix are at the back.
