## Intersection of Sets

The intersection of two sets A and B ( denoted by A∩B ) is the set of all elements that is common to both A and B. In mathematical form, For two sets A and B, A∩B = { x: x∈A and x∈B } Similarly for three sets A, B and C,

Venn Diagram was proposed in 1880 by John Venn. These diagrams are very useful tools to understand, to interpret and to analyze the information contained by the sets. The different region in the Venn Diagrams can be represented with unique mathematical notation. eg: (AUB), (AUBUC) etc.

For two sets A and B, the union of A and B (denoted by A∪B) is the set of all distinct elements that belong to set A or set B. In mathematical form, A∪B = { x: x∈A or x∈B}

A set is a collection of distinct objects(elements) which have common property. For example, cat, elephant, tiger, and rabbit are animals. When, these animals are considered collectively, it’s called set. Set Notation The members(elements) of set is separated by comma and braces { } are used outside the comma separated elements.

Let y = m1x + c1 and y = m2x + c2 be the equations of two lines in a plane where,
