Presents a thorough, no-frills introduction to trigonometry in the general context of functions and their graphs. Emphasizes the functional aspect of trigonometry including an introductory chapter on general ideas of functions and graphs. Covers exponential and logarithmic functions and the most important ideas from analytic geometry. Provides a large selection of exercises, half of them answered, ranging in difficulty from simple, straightforward checks on basic concepts, to problems that integrate several ideas and may involve applications. Features cumulative review exercises that cover...

Presents a coherent body of theory for the derivation of the sampling distributions of a wide range of test statistics.

Engineers and computer scientists who need a basic understanding of algebra will benefit from this accessible book. The sixth edition includes many carefully worked examples and proofs to guide them through abstract algebra successfully. It introduces the most important kinds of algebraic structures, and helps them improve their ability to understand and work with abstract ideas. New and revised exercise sets are integrated throughout the first four chapters. A more in-depth discussion is also included on Galois Theory. The first six chapters provide engineers and computer scientists with the...
