Math for Real Life: Teaching Practical Uses for Algebra, Geometry and Trigonometry PDF book by Jim Libby for free Download.


Make this book suit you. it can be read from cover to cover or used as a resource for when a certain topic is being covered. there are many times when a great application comes to mind, but well after the math topic is in the rear view mirror. 

this book might give information new to you or simply serve as a resource to fit applications to the appropriate places in the school year. the primary audience for this book is secondary math teachers (although anyone who has ever asked the question, “Where are we ever going to use this?” might find this book interesting reading). at the risk of insulting your intelligence, answers or steps to work out problems have been supplied throughout this book. 

i have confidence in your ability to work these out on your own. they are supplied only in the interest of clarity and of saving you some time. the problems here are not meant to be overly rigorous and take away from the main goal of the book. technically, there will be times when statements like “neglecting air resistance” or other such qualifications should be used. 

When it doesn’t create a major problem, those types of statements will usually go unmentioned. the goal here is not mathematical rigor, but getting students to feel more connected to the math they are learning. typically, units are in the english system. 

Like it or not, most students still have a better feel for this than for the metric system. there are times, such as certain scientific examples, when the metric system is the best to use. at times the system used is somewhat arbitrarily chosen. 
to help in finding material, topics have been grouped into typical secondary classes: algebra i, geometry, algebra ii, advanced Math, and trigonometry. obviously, there is some overlap and review in these courses, so topics have been placed generally in the courses in which they most commonly appear. for the most part, i have left out the areas of probability and statistics. 

Most students can easily identify areas of their application. Learning mathematics is, at times, a confusing, painful, joyless endeavor for many. Hopefully students will come to feel just a little more energized by seeing real world applications to this hard work they are doing.

"Where are we ever going to use this?" Every high school math student has asked this question. Often teachers themselves aren't sure how to respond. One answer is that higher mathematics learned in high school will be essential to learning yet more at the college level. A more satisfactory answer calls for an awareness of how math is applied in many specific areas.

Written primarily for teachers, this book presents hundreds of practical applications for mathematics--from baseball statistics to the theory of relativity--that can be understood by anyone with a knowledge of high school algebra, geometry and trigonometry.
