Plane TrigonometryMcGraw-Hill, 1980 - 295 sider This revision of a best-selling plane trigonometry text for freshmen and sophomores maintains the trademarks of clear, concise exposition coupled with graded problems. The result is a fresh and modern version of a classic text. Major changes include an emphasis on the use of calculators and calculator-related exercises, the use of radian measures appearing after Chapter 5 to help prepare students for analytic geometry or calculus, the expansion of Chapter 9 to include more applications as well as the addition of polar, exponential functions, and a greater emphasis on graphing. |
