Basic Technical College Mathematics

This book has been fully revised and is suited for technical schools, community colleges and proprietary schools. It is intended to provide readers with the math skills essential to a wide variety of industrial, technical and trade areas and can be used a mathematics supplement in content courses in areas like Drafting, Machine Technology, and Automotive Technology. The volume examines, fundamental operations in arithmetic, applied algebra, applied geometry, and trigonometry. For trade and industrial professionals.

Since the beginning of recorded history, mathematics has broadened the outreach of every civilization and generation. Today, with our knowledge doubling every five years, the role of mathematics in our everyday life cannot be overestimated. Mathematics has become essential to life itself. Every vocation requires some practical knowledge of mathematics. The major objective of the third edition of Basic Technical College Mathematics is to help you gain the mathematical skills you need in your chosen profession. To help you attain these skills, I have been careful to present mathematical concepts in words and examples that are simple to understand and easy to remember. Frequent use is made of mathematical problems which daily confront the technician and craftsman. Consequently, this book is written for you, the student, to learn mathematics in the most efficient manner. To provide additional essential mathematics, the third edition of Basic Technical College Mathematics includes three new chapters: Chapter 6-Basic Measurement, Chapter 7-Data, Graphs and Basic Statistics, and Chapter 13-Graphs and Linear Equations. Former Chapter 14-Construction of Simple Geometric Figures has been moved to the Appendix. These new chapters provide mathematics content that is becoming more important in solving daily practical problems. An extensive Mathematical Glossary assists learning. It is important to use this text properly to optimize your learning. Read the following description of the features in each chapter so you will understand how to use the text. Chapter Title:The chapter title gives you a glimpse of the contents of the chapter and enables you to rapidly select your area of study. Objectives:The objectives tell you what you will learn and what you will be able to do when you complete the chapter. Self-Test:Use the self-test to measure your need to study the chapter. If you do well with the self-test, you may already have a good comprehension of the material presented in the chapter. Thus, you may want to move on to the next self-test and the beginning of the next chapter. Definitions and Basics:A brief introduction of the topics and a glimpse of the concepts that are used in the chapter. Careful study of the definitions of mathematical terms is essential to fully understand and learn the topics covered in the chapter. Examples and Applications:This is the meat of the chapters. You are introduced to the mathematical skills and knowledge you need to master in order to meet the chapter objectives. The numerous examples and illustrations help you gain these skills and knowledge. Exercises including Applications:These problems give you practice in skills you have learned. Most often, the exercises are drawn from real-world problems and everyday experiences. Think Time:This feature gives you the opportunity to think of ways you can apply what you have learned. Perhaps you can think of problems you face in your profession that can be solved more effectively with what you have learned. Procedures to Remember:Mathematical procedures and operations you need to remember are written concisely and to the point. You will find these procedures to be of great help to you in solving problems quickly and efficiently. Chapter Summary:The chapter summary serves as a composite of all the information that has been presented within the chapter. It includes those concepts that must be learned for further development of your mathematical skills. Chapter Test:The test at the end of each chapter evaluates your ability to do the mathematical operations taught in the chapter. Wrong answers and/or procedures for solutions indicate the precise area where mathematical skills have not been properly or adequately developed. Correct answers and procedures indicate properly developed skills and your
