Solving Systems of Equations by Substitution is a second edition of a book written by Reginald Ray. It is the latest in a series of titles written for use by undergraduate students and this text is designed to help students familiar with the subject.
The book is designed to be used as a standalone course, although it also contains a number of other study books. It was designed to give students practice working with different systems of equations as well as how to solve them, so that they can learn to create more complex equations in later years. Students will find the book extremely useful but will also find that they learn several key principles relating to Algebra and Systems of Equations, which will also serve them in their future studies. As this is an online course, you should be able to access it from any PC.
It was reviewed by the US Government and found to have been written with the right academic standards. To ensure this, there are sections within the book which were written to meet the national standards, such as the need for proper grammar, spelling, and punctuation.
The book starts with a quick introduction to the subject of Systems of Equations. It goes through different types of Algebra which can be used to solve different systems. The book then gives detailed explanations of some of the most important concepts, such as: what are Euler’s method and how it works; what is Venn Diagrams; the Polynomial Equation System; the Power Series; and of course, What is a Solver?
It then explains the Traditional Method of solving equations and works through the uses of other methods such as the Ordinary Differential Equations, Sylow-Sylow Equations, Fourier Equations, Euler Equations, Fibonacci Equations, and the Anderson Equations. In addition, the book explains how to create graphing calculators using graphing software such as Logo or Maths Girl, how to use mathematical notation, and how to convert equations to and from other types of calculations. The book goes on to explain how to convert expressions like x^2+y^2 to definite expressions for the simplex integral.
Throughout the book there are examples of how to use various calculators to solve problems and convert expressions, as well as examples of how to use Venn Diagrams and Sylow-Sylow to do the same thing. You will also find many exercises that can help you work out your solutions to problems, as well as some great videos to help you understand the concepts better.
Many other books have used this format, but none have been quite so comprehensive as this one. It has been found to have a great level of detail and it also provides plenty of practice problems, some of which can help you build up your confidence in the areas that you need it most. Many other books offer the added benefit of teaching more than one part of the subject at a time, but it seems that the authors of this book have made an excellent choice in this regard.
The second edition is still available online and is more of a book for studying than a reference book. It includes the information that is found in the first edition as well as the advanced topics that were not in the first edition.
