PRECALCULUS prepares students for calculus and the rigors of that course, having been written by teachers who have taught the courses and seen where students need help--and where other texts have come up short. The text features precise definitions and exposition, carefully crafted pedagogy, and a strong emphasis on algebraic, transcendental, and trigonometric functions. To show students how important and relevant precalculus topics are to their future coursework, an optional Looking Ahead to Calculus feature appears in each chapter. The varied examples and exercises include many that encourage students to use and understand graphs, as opposed to simply draw them, providing additional sound preparation for calculus.
