It explains how to read key scales and perform core operations including multiplication, division, combined calculations, and squares or square roots. The book also covers trigonometric use for sines, tangents, and related small-angle functions, including handling significant figures, decimal-point placement, accuracy, and tolerance, with chapter-by-chapter methods and reference-style instruction.","SKILLFACT\"LIBRARY ·642  \n# simplify math:learn to useTHE SLIDE RULE\n\n0………luduu10000melodah|1中中gP5,Lld.:nlnlununbdluuln  uullnm²wtuwtuulwwwuwlwwywyw……  \n● Reading the scales  \n● Multiplication  \n● Division  \n● Combined operations  \n● Squares and square roots  \n● Trigonometric operations  \nsimplify math:learn to useTHE SLIDE RULE  \nby ElectronicTeaching Laboratories  \n# FIRST EDITIONFIRST PRINTING—JUNE,1966\n\nCopyright ⑥1966 by Editors and Engineers,Ltd.,NewAugusta,Indiana.Printed in the United States of America.  \nAll rights reserved.Reproduction or use,without expresspermission,of editorial or pictorial content,in any manner,is prohibited.No patent liability is assumed with respect tothe use of the information contained herein.While everyprecaution has been taken in the preparation of this book,no warranty is made and Editors and Engineers,Ltd.ex-pressly disclaims any liability for results of the use hereof,liability being assumed by the user hereof.  \nLibrary of Congress Catalog Card Number:66-23771  \n# PREFACE\n\nThe slide rule is an early mathematical\"computer,\"used for years by engineers,mathematicians,and experi-menters.All the usual drudgery of long-figure computa-tion of multiplication,division,squaring,cubing,loga-rithms,and trigonometry are reduced to easy solution bymechanical means.  \nA slide rule will give answers of three-or four-digitfigures,with an accuracy which is not off by more thanabout 1 percent.While this obviously will not be adequatefor problems in bookkeeping where you must be right tothe penny,it is sufficiently accurate for use in solvingproblems in electronics,engineering,mechanics,or othermathematical computations.  \nThe average slide rule provides scales for handlingsome of the most involved computations and combina-tions,and doing them easily.But if you go no furtherthan simple multiplication and division,you can saveconsiderable time in doing them,even on an inexpensiveslide rule.  \nThis book shows you how to perform a variety of mathcomputations from the simplest to the more involved.Itwill be especially valuable to students,hobbyists,engi-neering trainees,and others who need to perform arith-  \nmetic operations swiftly,simply,and accurately,andshould be an excellent reference companion to any sliderule.ELECTRONIC TEACHING LABORATORIES  \nCHAPTER 1  \nREADING THE SCALES-…---------  \n7  \nHistory of The Slide Rule—Buying A Slide Rule—Partsof A Slide Rule—Construction of The Scales-SignificantFigures—Primary NumbersSecondary Numbers—Ter-tiary Numbers—Accuracy and Tolerance  \nCHAPTER 2  \nMULTIPLICATION;THE C AND D SCALES…-…………33Multiplication With Logarithms—Method—Choice of In-dex—Locating The Decimal Point  \nCHAPTER 3  \nEDIVISION;RECIPROCALS AND THE CI SCALE…-   -  …45Division—Reciprocals—Scientific Notation—The CI Scale Use of The CI Scale for Multiplication  \nCHAPTER 4  \nCOMBINED OPERATIONS;THE CF AND DF SCALES…59The CF and DF Scales—Multiplieation by Pi(π)一Proportion  \n# CHAPTER 5\n\nSQUARES AND SQUARE RooTS;THE A AND B SCALES....69Squaring A Number—The A and B Seales—Using Loga-rithms To Find Squares—Finding The Square of a Num-ber—Using Logarithms To Find Square Roots—FindingThe Square Root of A Number—Combined Operationswith The A and B Scales  \n# CHAPTER 6\n\nSINES AND TANGENTS;THE S,ST,AND T SCALES--83The Scale Ranges—Placing The Decimal Point—For TanGreater Than 45°  \n# ANSWERS TO EXERCISES\n\nCHAPTER 1  \n# READING THE SCALES\n\nThe slide rule is a mechanical device for performingmathematical calculations.It can be used to solve prob-lems involving multiplication,division,square roots,cuberoots,logarithms,and trigonometry.It cannot be usedto add or subtract.  \nWith a little practice,accuracy and speed with the sliderule are quickly developed.Answers correct to 3 signifi-cant figures may be obtained from the popular-sized 10-inch slide rule.Longer slide rules provide better accuracyin the 4th significant figure,but they are not as conveni-ent in size.The 6-inch pocket slide rules are very con-venient ","cbCaivtcsLq7obov","https://ap.wps.com/l/cbCaivtcsLq7obov","pdf",2774283,6,1,100,"English","en",105,"# Preface\n## Reading the Scales\n## History of The Slide Rule\n## Buying A Slide Rule\n## Parts of A Slide Rule\n## Construction of The Scales\n## Accuracy and Tolerance\n# Multiplication;
