Here is a helpful reference work designed for the college science student needing a quick explanation of the mathematics found in the first two years of the college science curriculum. Rather than giving lengthy explanations of abstract mathematical theory, this useful handbook focuses on math as a scientist's working tool. Part reference and part reminder-the volume reinforces the student's previous knowledge of math and guides the reader through the many unfamiliar mathematical computations that are part of his or her science requirements. Numerous examples throughout the book are drawn from actual situations encountered in science courses. The chapters may be used in any sequence and are extensively cross-indexed for user convenience. Demonstrating how formal course work in chemistry, physics, astronomy, and the other sciences employ certain vital areas of mathematics, the book covers a broad range of important subjects, including reporting and analyzing uncertainty, units and dimensions, graphs, the simple functions of applied math, statistics, quadratic and high power equations, and simultaneous equations. Other chapters are devoted to determinants, vectors, complex numbers, calculus-differentiation, integration, series and approximations, common differential equations, and differential operators. The book contains many useful reference tables and summaries of formulas and techniques. A valuable study aid for every science student and an auxiliary reference work certain to be used frequently, USED MATH gives solid explanations and examples of the "old and used" math fundamental to all science courses.
