FAQs on Sets Basics Video Lecture - Applied Mathematics for Class 11 - Commerce
| 1. What is a set in mathematics? |  |
| 2. How is a set represented? | |
Ans. A set is typically represented by listing its elements within curly braces {}. For example, a set of even numbers can be represented as {2, 4, 6, 8, ...}, where the ellipsis (...) denotes that the pattern continues.
| 3. What is the cardinality of a set? | |
Ans. The cardinality of a set refers to the number of elements it contains. It is denoted by the symbol |A|, where A is the set. For example, if A = {1, 2, 3}, then |A| = 3, indicating that the set A has three elements.
| 4. What is the difference between a subset and a proper subset? | |
Ans. A subset is a set that contains all the elements of another set, including the possibility of being equal to the other set. On the other hand, a proper subset is a subset that contains all the elements of another set, but it is not equal to the other set. In other words, a proper subset is a strict subset.
| 5. How can set operations be performed? | |
Ans. Set operations, such as union, intersection, and complement, can be performed to manipulate and analyze sets. The union of two sets A and B is the set containing all elements from both sets. The intersection of two sets A and B is the set containing only the elements that are common to both sets. The complement of a set A, denoted by A', is the set of all elements that are not in A. These set operations allow for various calculations and comparisons within sets.
