Finite set & Infinite set fully expained|Mathematics|

Finite Set vs Infinite Set:
Finite Set
1. *Definition*: A set with a limited or finite number of elements.
2. *Characteristics*:
1. Has a limited number of elements.
2. Can be represented using roster form (listing all elements).
3. Can be counted.
3. *Examples*:
1. A = {1, 2, 3, 4, 5}
2. B = {a, b, c}
3. C = {1, 3, 5, ..., 99}
Infinite Set
1. *Definition*: A set with an unlimited or infinite number of elements.
2. *Characteristics*:
1. Has an unlimited number of elements.
2. Cannot be represented using roster form.
3. Can be represented using set-builder form (using a rule to define elements).
3. *Examples*:
1. Natural numbers: ℕ = {1, 2, 3, ...}
2. Integers: ℤ = {..., -3, -2, -1, 0, 1, 2, 3, ...}
3. Real numbers: ℝ = {all rational and irrational numbers}
Key differences:
1. *Number of elements*: Finite sets have a limited number of elements, while infinite sets have an unlimited number of elements.
2. *Representation*: Finite sets can be represented using roster form, while infinite sets cannot.
3. *Countability*: Finite sets can be counted, while infinite sets cannot.
Real-World Applications:
1. *Computer science*: Finite sets are used in programming, while infinite sets are used in theoretical computer science.
2. *Mathematics*: Finite sets are used in algebra and geometry, while infinite sets are used in calculus and topology.
3. *Data analysis*: Finite sets are used in data analysis, while infinite sets are used in statistical modeling.
