समुच्चयों का कार्तीय गुणनफल
In Class 11 Mathematics, under Relations and Functions, students learn how to form the Cartesian product of two sets as the set of all possible ordered pairs (a, b), where a belongs to the first set and b to the second. The topic explains why the order of elements matters, how to represent products using roster form and diagrams, and how to find their number of elements. This foundation helps students describe relations as subsets of a Cartesian product and understand domain and codomain.
TOPIC PRACTICE
Up to 1 questions from this page. Select your focus, then start.
Any relation from A to B is a subset of A×B because the first element of each ordered pair belongs to A and the second belongs to B. A function is a special relation in which every element of A has exactly one image in B. Hence, f⊆A×B. Exam tip: For a function from A to B, the order is domain first and codomain second, so choose A×B rather than B×A.
