List of chapters of NCERT 11th Maths Book along with weightage, details of important topics, etc, are mentioned below:

Unit 1 Sets and Functions

Sets and functions topic holds a weightage of 23 marks out of 80 marks theory exam. Chapters included in Sets and Function are listed below:

Sets

One cannot think of modern-day mathematics without the concepts of sets, nowadays this concept is being used in almost every field of mathematics. Sets are used to define various mathematical concepts like relation and functions, geometry, sequences, probability, etc.

Important concepts addressed in 11th maths chapter 1 are listed below.

• Sets and their Representation
• Empty Set
• finite and Infinite Sets
• Equal Sets
• Subsets
• Power Set
• Universal sets
• Venn diagram
• Operations on sets
• The complement of a set

Relations and Functions

Mathematics is all about finding a pattern or a recognizable link between the quantities that change. A relation involves pairs of objects in a certain order. This chapter deals with how to link pairs of objects from two sets, how to establish a relation between the two objects in a pair, and special relations that qualify to function.. The concept of function is very important in mathematics as it captures the idea of a mathematically accurate correspondence between one quantity and the other.

Important concepts addressed in 11th maths chapter 2 are listed below.

• Cartesian Product of sets
• Relations
• Functions

Trigonometric Functions

Trigonometry is used in many fields, such as the study of seismology, the construction of electrical circuits, the explanation of the condition of the atom, the calculation of tidal heights in the seas, the examination of musical tones and many others. This Chapter includes generalizing the concept of trigonometric ratios to trigonometric functions and studying their properties.

Important concepts addressed in 11th maths chapter 3 are listed below.

• Trigonometric Functions
• Trigonometric Function of Sums and difference of two angles
• Trigonometric equations

Unit 2 Algebra

Algebra topic holds a weightage of 30 marks out of 80 marks theory exam. Chapters included in the algebra section are listed below:

Principle of Mathematical Induction

This chapter introduces students to mathematical induction. The Principle of Mathematical Induction is a well-adapted principle used in many mathematical disciplines to solve equations and statements formulated in terms of n, where n is a positive integer.(Deleted from the syllabus for the academic session 2020-21)

Complex Numbers and Quadratic Equations

Complex numbers is a very important chapter of the curriculum which introduces students with concepts like imaginary numbers, argand plane, modulus of complex numbers etc, with the main objective to help students solve equations like ax2+bx+c=0 where D=b2-4ac<0, which is not possible in the system of real numbers.

Important concepts addressed in 11th maths chapter 5 are listed below.

• Complex numbers
• Algebra of complex numbers
• Argand and polar representation
• Modulus and conjugate of a complex number

Linear Inequalities

Linear inequality involves inequalities of linear function, which is usually solved using equations and graphical methods. In this Chapter one will learn concepts of linear inequalities in one and two variables. The study of inequalities is very useful in solving problems in the field of science, mathematics, statistics, economics, psychology, etc.

Permutations and Combinations

This chapter introduces students to one of the most interesting topics of mathematics i.e Permutations and Combinations. Permutation is arranging a number of objects in a definite order taken at a time.

Important concepts addressed in 11th maths chapter 7 are listed below.

• Fundamental principle of counting
• Permutation
• combination

Binomial Theorem (Deleted from the syllabus for the academic session 2020-21)

Binomial theorem helps students to conceptualize a widely used concept for expanding high power numbers and variables like 9876, 5343etc. This chapter provides an easier way to expand (a+b)n, where n is an integer or a rational number.

Important concepts addressed in 11th maths chapter 8 are listed below.

• Binomial theorem for positive integral indices
• General and middle term

Sequences and Series

Sequences chapter provides information about some new concepts of A.M. In addition to discussing more on A.P. in this chapter;it also discusses arithmetic mean, geometric mean, relationship between A.M. And G.M., special series in sum to n terms of consecutive natural numbers, sum to n terms of natural number squares and sum to n terms of natural number cubes.

Unit 3 Coordinate Geometry

Coordinate Geometry topic holds a weightage of 10 marks out of 80 marks theory exam. Chapters included in Coordinate Geometry section are listed below:

Straight Lines

You already know what a straight line is, and you might have drawn loads of straight lines on graph papers. This chapter will however introduce you to many important straight line concepts. It can delve into subjects such as a line's slope, two-line tilt, two-point collinearity, and several other such topics.

Important concepts addressed in 11th maths chapter 10 are listed below.

• Slope of a line
• Various forms of the equation of a line
• General equation of a line
• Distance of a point from a line

Conic Sections

This chapter includes chapter curves, particularly circles, ellipses, parabolas and hyperbolas. These curves are, in fact, known as conic sections or, more commonly, conic ones, because they can be obtained as intersections of a plane with a double napped right circular cone. These curves have a very wide range of applications in fields such as planetary motion, design of telescopes and antennas, reflectors in flashlights and automobile headlights, etc.

Important concepts addressed in 11th maths chapter 11 are listed below.

• Sections of a cone
• Circle
• Parabola
• Eclipse
• Hyperbola

Introduction to Three Dimensional Geometry

We need three reference planes to define the position of an object in space. The three numbers representing the three distances are referred to as point coordinates with reference to the three coordinate planes. In this chapter, students will study the basic concepts of geometry in three-dimensional space.

Important concepts addressed in 11th maths chapter 12 are listed below.

• Coordinate axis and planes in three-dimensional space
• Coordinate of a point in space
• Distance between two points
• Section Formula

Unit 4 Limits and Derivatives

This chapter is an introduction to the Calculus section. Calculus is the branch of mathematics, which deals mainly with the study of change in the value of a function as a domain change point. Limits and derivatives topic holds a weightage of 7 marks out of 80 marks theory exam. Chapters included in Limits and derivatives section are listed below:

Limits and Derivatives
