1. What is a Set Notation?

Ans. Sets and Functions are one of the most important topics covered in Class 11 Mathematics. It includes the concept of set notations. Set notations are used to list things, such as numbers, inputs, or outcomes. You might have noticed the “{ }” symbol in the chapter. They are called curly brackets and are used by set notations. The elements of a set are put inside these brackets.

2. What are the different types of Functions?

Ans. NCERT Solutions for Class 11th Mathematics cover the sums of functions. It defines a function as the relation between a set of inputs and a set of permissible outputs. Each input in these sets is related to exactly one output. These are the following types of functions.

Identity Function

Constant Function

Polynomial Function

Quadratic Function

Cubic Function

Rational Function

Modulus Function

3. What do you mean by coordinate Geometry?

Ans. The exact position of a point in a coordinate plane can be ascertained using coordinates. Coordinate Geometry is the study of geometry using coordinate points. Coordinate geometry is used in the following ways.

Finding the area of a triangle on a Cartesian plane.

Dividing a line into m:n ratio.

Calculating the distance between two points.

Finding the midpoint of a line.
