Uncover the mysteries that lie within your calculator This remarkable book explores the simple internal calculatorprocesses—algorithms and programs—that tell us, forexample, that the cosine of 56? is 0.5591929035. Using carefullyconstructed diagrams and figures, the author effectivelydemonstrates how calculator keys compute powers, roots, logarithms,and trigonometry functions, while also providing insights intosimple programming, the conversion between decimal and binarynumeration, and perhaps most importantly, the structure of ournumeration systems. Many people believe that the processes thatdrive calculators demand advanced mathematical concepts; however,this book proves that a minimal understanding of algebra andgeometry is all that is needed to follow the step-by-stepexplanations of how scientific calculators work. Inside Your Calculator: From Simple Programs to SignificantInsights is a complete and multifaceted exercise in criticalthinking. This book features: A detailed explanation of how to use a graphics calculator andprogram basic functions A discussion of the history of mathematics when appropriate,which provides a foundation for further learning Fundamental mathematical lessons and interesting applications ofpre-calculus mathematics A thorough review of the fundamentals of programming, algebra,and geometry needed to gain insight into why the algorithms workand how the results are meaningful in our lives While the simultaneous use of a calculator is not needed to gaininsight into how the algorithms work, those who do have aprogrammable graphics calculator can experiment with the programspresented in the book. These programs may be used on TI-84 andTI-83 calculators, and additional information for other TexasInstruments calculators as well as the Casio FX series is availableon the book's related web site. As a result of over fifty years of award-winning teachingexperience in both high school and college classrooms, Dr. Risinganticipates and answers potential questions from readers, and hesuccessfully brings this subject alive in an illuminating andentertaining way. This book is therefore not only ideal forundergraduate mathematics majors as either a primary orsupplemental text, but it also appeals to anyone with an interestin mathematics and its ideas.

A revolution is ongoing in the field of small-scale energy solutions, which can enable lower impact on the environment, more robust supply and self-determination. Solar power and other forms of renewable energy sources, which you can implement to generate your own electricity, are growing quickly. Electromobility is transforming the car industry and transportation systems and can also play a role in your energy system. Electricity can be used much more efficiently than before, for example by using LED light, variable speed motor drives and efficient home appliances. Smart controls are available, sometimes with free open source software. All this opens up tremendous opportunities for energy independence, which is the focus of this book. The book introduces the reader to a number of renewable energy sources, to different options for storing electricity and to smart use of electricity, particularly in the context of small isolated systems. This is important because many renewable energy sources are weather- and season-dependent and usually require storage and smart control, in order to obtain a system that is completely independent of the electricity grid. In the book, overall system design is explained, including how to combine different sources in a hybrid system. Different system sizes and architectures are also covered. A number of real cases are described, where homes, businesses and communities have achieved a high level of energy independence or are on their way to achieving it. This book will prove useful in university education in renewable energy at bachelor and master level, and also for companies and private individuals, who want to start or expand activities in the area of renewable energy.
