About the Author
This comprehensive pocket reference guide gives students, engineers, toolmakers, metalworkers, and other specialists a wide range of mathematical and physical formulas in a handy format.
Compactly arranged in an attractive, unique style, this reference book hasjust about every equation, definition, diagram, and formula that a user might want in doing undergraduate-level physics and mathematics. Great care has been taken to present all formulas concisely, simply, and clearly. All of the information included is practical—rarely used formulas are excluded.
Thoroughly practical and authoritative, this book brings together in three parts thousands of formulas and figures to simplify review or to refresh your memory of what you studied in school. If you are in school now, and you don’t have a lot of time but want to excel in class, this book will help you brush up before tests, find answers fast, learn key formulas and geometric figures, study quickly, and learn more effectively. In fact, each year, this indispensable study guides helps hundreds of thousands of students improve their test scores and final grades.
The first part of the book covers the International System of Units (the SI base units, the SI derived units,the SI prefixes, and units outside the SI that are accepted for use with the SI); metric units of measurement; U.S. units of measurements; and tables of equivalent metric and United States Customary System (USCS) units.
The second part of the book covers formulas, rules, and figures related to Algebra, Geometry, Trigonometry, Analytical Geometry, Mathematics of Finance, Calculus, and Statistics.
The third part of the book covers formulas, definitions, and figures related to Mechanics, Fluid Mechanics, Temperature and Heat, Electricity and Magnetism, Light, and Waves and Sound.
New in the Second Edition
This edition features essentially the same format and organization as the first edition. In addition to improved figures and new text, enhancements and extensions of several sections in the first edition have been included, and two new sections in Part II have been added.
• In Part I (concerning Units), a section on units of measure in precious metals has been added.
• In Part II (concerning Mathematics), the section on calculus has been expanded, and two new sections on Arithmetic and Mathematical Fundamentals for Computer Science have been added.
Students and professionals alike will find this book a very effective learning tool and reference.
