The chapter also explores Power set, Universal set, Venn diagrams, Union and Intersection of sets, Difference of sets, and Complement of a set.

Chapter 2 Relations & Functions

This chapter is an introduction to the concept of relation and functions. In class 11 NCERT maths, you are going to learn half of the relations and functions. In our life, there are well-defined relations like mother and father, brother and sister, etc. In a similar way, you can form relations in mathematics. A relation from a set A to a set B is said to be a function if every element of set A has one and only one image in set B. Functions are very important in the case of data analysis. Most of the higher-level examination tests your knowledge over the chapter relations and functions. The chapter is very important for schools as well as exams like JEE and CAT.

Class 11 Maths Chapter 2, Relations and Functions, includes various topics such as Ordered pairs, Cartesian product of sets, the number of elements in the cartesian product of two finite sets, and the Cartesian product of the reals with itself (upto R× R× R). The chapter also covers the definition of relation, pictorial diagrams, domain, co-domain and range of a relation. It explains Function as a special kind of relation from one set to another, pictorial representation of a function, domain, co-domain and range of a function. Real valued function of the real variable, domain and range of these functions, constant, identity, polynomial, rational, modulus, signum and greatest integer functions with their graphs. The chapter concludes with Sum, difference, product and quotients of functions.

Chapter 3 Trigonometric Functions

Trigonometry is the chapter that evolves around a right-angle triangle. The chapter was in class 10th where you have gone through the properties and usage of the properties. You have also done its application in daily life through chapter heights and distances. Here in class 11 NCERT maths, you will study a bit higher level of trigonometry.

The chapter also introduces the Fundamental Theorem of Algebra and examines the solution of quadratic equations within the complex number system.

Chapter 6 Linear Inequalities

We have studied how to solve linear equations in our high school classes. For example, if three pen and two scales cost 40 rupees and if 5 pen and six scales cost 80 rupees, to find the cost of pen and scale we use linear equations. Now consider the situation that you have given 120 rupees and you are asked to buy the maximum number of books that cost 33 rupees. This type of problem is formulated using linear inequality. That is if you can bye x number of books then 33x = 120. This is how linear inequality problems are formulated.

Chapter 6 of Class 11 Mathematics covers the topic of linear inequalities. The course examines algebraic methods of solving linear inequalities in one variable and represents them on the number line. Additionally, the chapter delves into the graphical solution of linear inequalities in two variables.
