商品簡介
Zill and Dewar revise the longer of their two precalculus textbooks for use in courses that are either longer than some or consider topics not covered in the shorter textbook. They continue to emphasize the function concept while making an additional effort to reinforce algebraic and trigonometric skills. The examples and exercises allow students to practice such operation as factoring, expanding a power of a binomial, completing the square, synthetic and long division, rationalization, and solving inequalities and equations in situations similar to those they will encounter in calculus.
