Subsets
If A and B are sets such that each element of A is an element of B, then we say that A is a subset of B and write A B. ..
If A and B are sets such that each element of A is an element of B, then we say that A is a subset of B and write A B. ..Find the number of 3 element subsets that can be formed from the set {..
Find the number of 3 element subsets that can be formed from the set {a, b, c, d, e, f, g, h} . => 6 or 56 or 336 or 1..
Proof:
The null set f is a subset of every set, in particular f A. By hypothesis, A f . The two conditions imply A = f..
Question 3
Question: Write down the following statements using set notation. (i) x is an element of set A (ii) y is not an element of set (iii) A is a subset of B (iv) A is a proper subset of B (v) A contains B (vi) A is superset of B (vii) Neit..

Properties of Relations - Consider the set A = {a, b, c, } then any subset of A x A is called a relation in A. Let R be any relation in A so that R is a subset of the product set A x A. We will discuss the properties a relation may possess.Consider the set A = {a, ..
Relations and Functions
Relations and Functions - In our daily life, we come across many relations such as father-son, brother-sister, teacher-student and many more. In mathematics too, we come across relations such as . A is a subset of B . line l is parallel to line m . number m is less than number n . In all ..
Relations
If A and B are two non-empty sets, then a relation R in A x B is a subset of A x B. If we use the letter R to denote a relation, then we can write the relation between a and b as aRb a is related to b..

An ordered pair has a pair of elements which occur in a definite order. Cartesian Product - Given two sets A and B, all possible ordered pairs (x, y) obtained such that x A and y B is called the cartesian product of the sets A and B and is denoted by A ..
Question 1
Question: What is a solution set? Answer: The subset of the replacement set which satisfies the values of the variable is called the solution set. Example: Solution set= {1..

A real valued function f : A to B or simply a real function 'f ' is a rule which associates to each possible real number x A, a unique real number f(x) B, when A and B are subsets of R, the set of real numbers. In other words, functions whose domain and co-d..
