DESCRIPTION
Essential reference for practical math work: this classic Bowser guide explains how and why logarithms simplify calculations, and how to use tables for real-number problems.
This edition presents the fundamentals of logarithms and trigonometric tables, focusing on clear rules, step-by-step methods, and practical examples. It covers how to compute logarithms, how to handle products, quotients, powers, and roots, and how mantissas and characteristics form the complete logarithm. Readers will learn to apply the rules to numbers of one to four figures and beyond, with explanations that emphasize usable techniques for quick, accurate results.
- Grounded explanations of preliminary notions, including the base-10 system and the meaning of mantissa and characteristic
- Guided procedures for finding logarithms and their corresponding numbers across common cases
- Practical notes on accuracy, rounding, and the tabular differences used to speed calculations
- Illustrative methods for estimating logarithms of larger numbers and for reversing the process to recover numbers from a given logarithm
Ideal for students and professionals who need reliable, hands-on access to logarithmic and trigonometric tables in a compact, historical reference.
