# Introduction to Algebra for Engineering

## This free online course explains the various approaches and methods used for solving algebraic problems in engineering.

Publisher: ADU## Description

There are many situations in engineering, where we have to deal with algebraic symbols and equations. The aim of this course is to take young and aspiring engineers through the fundamentals of algebra in engineering. This free online course begins by defining binary operations. The course explains how an operation, such as addition or multiplication is performed on a set, giving rise to two elements to combine to form a third element. The course also describes some of the typical properties of a system. This course defines a Group as consisting of a non-empty set G, with a binary operation (∗) on G and properties including closure, associative, identity elements and inverse elements. The course also differentiates between infinite and finite commutative groups. A Field consists of a non-empty set F, with two binary operations, (+,•). You will learn how It is customary to denote the two operations as (+) and (•) due to variances in their behaviour. You will learn about a new set of numbers known as imaginary numbers or pure imaginary numbers. You will learn how the imaginary unit is defined. You will also learn how to perform operations on imaginary numbers and on complex numbers.

Complex numbers combine the set of real numbers with the set of pure imaginary numbers. In this course, you will learn how a set of complex numbers form a field under the operations of addition and multiplication. You will also learn how to graph complex numbers and how to perform operations on complex numbers. This course defines relations as any set of ordered pairs and ranger sets as a set of second coordinates of each ordered pair. You will learn about a function which is any relation in which no two ordered pairs have the same first element. You will also learn about the functional notation and special functions. This course explains how constant functions map real numbers. The course describes the algebraic definitions of the absolute value function and the geometric definition of the absolute value function. You will learn about linear functions and the greatest integer function. This course goes deep in explaining the quadratic function as well as the concept of the parabola and the vertex. You will be introduced to the polynomial and rational functions. You will also be taken through the applications of exponential functions.

Finally, you will learn to perform arithmetic operations on functions. You will learn about the composition of functions and how to form the composite of two or more functions. You will also learn about the meaning of the inverse of a function and how to determine when the inverse exists. This course explains the form of a quadratic equation. The course explore the graphical solution of quadratic equations in more detail as well as other methods of solving quadratic equations. Also, you will analyze how to solve quadratic equations by using the Completing the Square method. This course further explains the conditions that must exist before the CTS method can be used for solving QEs. Learn how any quadratic equation can be solved using the quadratic formula. There are different types of problems that depend on their solution on analyzing quadratic functions and/or solving quadratic equations. In this course, you will learn some of the problem types from your work in previous algebra courses. We will examine some problems whose solutions depend on quadratic functions. Start this course today, and become better equipped in solving algebraic problems.
