Examples of Roster Method
- The formula for the first five natural integers, designated as set X, is X = {6, 7, 8, 9}
- The letter combinations {D, L, H, I} make up the set A of the word DELHI.
The Roster Method is another name for this approach of defining sets. Any order may be used to list the components of the roster set. As a result, the set {A, B, C, D} may be expressed as {B, A, C, D}.
Set-Builder Notation
Set-builder Notation is a type of mathematical notation used to describe sets by naming their components or highlighting the requirements that each member of the set must meet. Sets are written in the form of {y | (properties of y)} OR {y : (properties of y)} in the set-builder notation, where the condition that fully characterizes each member of the collection replaces the attributes of y.
The elements and properties are separated using the character ‘|’ or ‘:’ The entire set is interpreted as “the set of all elements y” such that (properties of y), while the symbols ‘|’ or ‘:’ are read as “such that.”
This article explores the set-builder notation, symbols used in set-builder notation, examples, representation of sets methods, etc.
