Aperçu

Welcome to the course material on Binary Operations in Further Mathematics. In this topic, we delve into the fundamental concept of binary operations and their applications in problem-solving and various mathematical structures.

Binary operations are operations that involve two elements to produce a unique element in a set. Understanding binary operations is essential in various mathematical disciplines as they form the basis of algebraic structures.

One of the primary objectives of this course is to help you grasp the concept of binary operations. You will learn how to identify different types of binary operations such as addition, multiplication, and composition. By understanding the properties of binary operations, you will be equipped to apply them effectively in solving complex mathematical problems.

Properties such as closure, commutativity, associativity, and distributivity play a significant role in binary operations. **Closure** refers to the property where the result of a binary operation on two elements remains within the same set. **Commutativity** implies that the order of elements does not affect the outcome of the operation. **Associativity** states that the grouping of elements does not alter the result. **Distributivity** involves the interaction of two operations, usually addition and multiplication, over a set.

Furthermore, you will explore the idea of sets defined by a property and set notations. **Set notations** provide a formal way of representing sets and their elements. Understanding **disjoint sets**, **universal sets**, and **complement of sets** will be crucial in your journey through this topic.

Venn diagrams are powerful tools used to visualize relationships between sets. They aid in solving problems involving set operations and relationships. By mastering the use of sets and Venn diagrams, you will enhance your problem-solving skills and tackle advanced mathematical concepts with ease.

In conclusion, this course material aims to empower you with the knowledge and skills necessary to navigate the world of binary operations confidently. By the end of this course, you will not only understand the intricacies of binary operations but also be able to apply them proficiently in diverse mathematical scenarios.

Note de cours

In mathematics, a binary operation is a calculation that combines two elements (operands) to produce another element. This operation is fundamental in algebra and appears throughout various mathematical structures such as sets, groups, rings, and fields. Understanding binary operations is crucial for advancing in abstract algebra and other higher-level math topics.

Question 1 Rapport

A binary operation * is defined on the set T = {-2,-1,1,2} by p*q = p $^{2}$ + 2pq - q $^{2}$ , where p,q ∊ T.
Copy and complete the table.

*	-2	-1	1	2
-2		7		-8
-1		2	-2
1	-7			1
2		-1

Réponse

p*q = p $^{2}$ + 2pq - q $^{2}$

when p = -2 and q = -2

p*q = -2 $^{2}$ + 2(-2)(-2) - (-2) $^{2}$
p*q = 4 + 8 - 4 = 8

when p = -2 and q = -1
p*q = -2 $^{2}$ + 2(-2)(-1) - (-1) $^{2}$
p*q = 4 + 4 - 1 = 7

when p = -2 and q = 1
p*q = -2 $^{2}$ + 2(-2)(1) - (1) $^{2}$
p*q = 4 - 4 -1 = -1

when p = -1 and q = -2
p*q = -1 $^{2}$ + 2(-1)(-2) - (-2) $^{2}$
p*q = 1 + 4 - 4 = 1

when p = -1 and q = -1
p*q = -1 $^{2}$ + 2(-1)(-1) - (-1) $^{2}$
p*q = 1 + 2 -1 = 2

when p = -1 and q = 2
p*q = -1 $^{2}$ + 2(-1)(2) - (2) $^{2}$
p*q = 1 - 4 - 4 = -7

when p = 1 and q = -2
p*q = 1 $^{2}$ + 2(1)(-2) - (-2) $^{2}$
p*q = 1 - 4 - 4 = -7

when p = 1 and q = -1
p*q = 1 $^{2}$ + 2(1)(-1) - (-1) $^{2}$
p*q = 1 - 2 - 1 = -2

when p = 1 and q = 1
p*q = 1 $^{2}$ + 2(1)(1) - (1) $^{2}$
p*q = 1 + 2 - 1 = 2

when p = 1 and q = 2
p*q = 1 $^{2}$ + 2(1)(2) - (2) $^{2}$
p*q = 1 + 4 - 4 = 1

when p = 2 and q = -2
p*q = 2 $^{2}$ + 2(2)(-2) - (-2) $^{2}$
p*q = 4 - 8 - 4 = -8

when p = 2 and q = -1
p*q = 2 $^{2}$ + 2(2)(-1) - (-1) $^{2}$
p*q = 4 - 4 - 1 = -1

when p = 2 and q = 1
p*q = 2 $^{2}$ + 2(2)(1) - (1) $^{2}$
p*q = 4 + 4 - 1 = 7
when p = 2 and q = 2
p*q = 2 $^{2}$ + 2(2)(2) - (2) $^{2}$
p*q = 4 + 8 - 4 = 8
