Here you will learn what is set builder form and how to represent sets in set builder form with examples.<\/p>\n
Let’s begin –<\/p>\n
Definition<\/strong> : In this form, a set is described by a characterizing property P(x) of its elements x. In such a case the set is described by {x : P(x) holds} or, {x | P(x) holds}, which is read as ‘the set of all x such that P(x) holds’. The symbol ‘|’ or ‘:’ is read as ‘such that’.<\/p>\n In other words, in order to describe a set, a variable x (say) (to denote each element of the set) is written inside the braces and then after putting a colon the common property P(x) possessed by each element of the set is written within the braces.<\/p>\n Example 1<\/strong><\/span> : The set E of all even natural numbers can be written as<\/p>\n E = {x : x is a natural number and x = 2n for n \\(\\in\\) N}<\/p>\n or, E = {x : x \\(\\in\\) N, x = 2n, n \\(\\in\\) N}<\/p>\n or, E = {x \\(\\in\\) N : x = 2n, n \\(\\in\\) N}<\/p>\n Example 2<\/strong><\/span> : The set A = {1, 2, 3, 4, 5, 6, 7, 8} can be written as A = {x \\(\\in\\) N, x \\(\\le\\) 8}.<\/p>\n Example 3<\/strong><\/span> : The set of all real numbers greater than -1 and less than 1 can be described as {x \\(\\in\\) R : -1 < x < 1}.<\/p>\n Example 4<\/strong><\/span> : The set A = {0, 1, 4, 9, 16, ….} can be written as A = {\\(x^2\\) : x \\(\\in\\) Z}.<\/p>\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" Here you will learn what is set builder form and how to represent sets in set builder form with examples.
