CBSE Notes Class 11 Maths Chapter 1 Sets

Let’s see what do we know about sets:

  • A set is a group or collection of objects or numbers, considered as an entity unto itself. Sets are usually symbolized by uppercase, italicized, boldface letters such as A, B, S, or Z. Each object or number in a set is called a member or element of the set. Examples include the set of all computers in the world, the set of all apples on a tree, and the set of all irrational numbers between 0 and 1
  • When the elements of a set can be listed or denumerated, it is customary to enclose the list in curly brackets. Thus, for example, we might speak of the set (call it K) of all natural numbers between, and including, 6 and 11 as:

K = { 6, 7, 8, 9, 10,11}
