Trigonometry
This eighth edition preserves the popular format and style of the previous editions. It is a standard right triangle approach to trigonometry, providing a smooth and integrated development of the six trigonometric functions from point-on-the-terminal-side, to right triangle, to circular function definitions. Nearly every section is written so that it can be discussed in a typical class session. The focus of the text is on understanding the definitions and principles of trigonometry and their applications to problem solving
