Barron's Educational Series, 2005 - Mathematics - 458 pages
2 Reviews
An experienced math instructor and teacher trainer helps to make PreCalculus easy--even for students who feel intimidated by more advanced math topics. His orderly, step-by-step approach begins with concepts and skills typically introduced in a first-year high-school-level algebra course then progresses to advanced algebra and trigonometry, needed for the study of calculus. The lesson format and step-by-step demonstration examples are designed for self-teaching and rapid learning. Special math tips help resolve student difficulties and are strategically located throughout the text. Major topics include: algebra; graphs and graphing calculator methods; complex numbers; polynomial and rational functions; exponential and logarithmic functions; fitting lines and curves to data; trigonometry and polar coordinates; conic sections and parametric equations; counting and probability; binomial theorem; and probabilities. Check-up exercises at the end of each chapter help students monitor their progress.

About the author (2005)

Lawrence S. Leff has helped make mathematics and tests more accessible to students through his work and his writing. Leff is assistant principal and math supervisor at Franklin D. Roosevelt High School in Brooklyn, New York. His writing is centered primarily on examination preparation guides. His books, which target high school students, have included, Let's Review: Sequential Mathematics, a teacher planning and student review and math test preparation guide, and Preparation for the CLEP--College-Level Examination Program. Some of Leff's math review guides originally were intended for New York area high school students participating in the three-year mathematics curriculum there. Lawrence Leff has also published mathematics materials not strictly for test-taking, including Geometry the Easy Way.
