Chapter 1 Sets A set is a well-defined collection of distinct objects. Well-defined collection means that there exists a rule with the help of which it is possible to tell whether a given object belongs or does not belong to given collection. Generally sets are denoted by capital letters A, B, C, X, Y, Z etc.

1. Representation of Sets- Usually, sets are represented in the following ways 2. Roaster form or Rabular form- In this form, we list all the member of the set within braces (curly brackets) and separate these by commas. For example, the set of all even numbers less than 10 and greater than 0 in the roster form is written as: A = {2,4, 6,8}

Chapter 2 Relations and Functions Function can be classified into two categories: 1. One-one or Many-one 2. Into or Onto Each of above category comprises entire gamut of function. Thus if a function is not one-one, it has to be many-one and vice-versa.

Similarly if function is into then it cannot be onto and converse.

One-one functions (Injective): A function is said to be one - one if for every value of x in the Domain, there exists one and only one value in co-domain.

Two different values of x do not have same value of y.

Many-one functions: A function is said to be many-one if there exists at least two elements in domain which have same image in co-domain.

Into functions: If there exist at least one element in co-domain which doesn't have a pre-image then such functions are said to be into.

Onto functions (Surjective): If there doesn't exist any element in co-domain which does'nt have a pre-image then such functions are said to be onto. Note that for onto function co-domain = Range.

Based on above two categories of function, we can classify functions into four type One-one and Onto (Bijective) One-one and Into Many-one and Onto Many-one and Into NCERT Solutions for Class 11 Maths Chapter 2 Relations and Functions Exercise 2.1 Exercise 2.2 Exercise 2.3 Miscellaneous Exercise

Chapter 3 Trigonometric Functions Literally, the word 'trigonometry' means the study of the properties of triangles. This involves the measurement of angles and lengths. An angle is defined as the amount of rotation of a revolving line with respect to a fixed line. If the rotation is in anticlockwise sense, the angle is taken to be positive, otherwise negative.

Basically, we use two types of systems to measure an angle, viz., the sexagesimal system (or English system) and the circular system. In the former, a right angle is divided into 90 equal parts and each part is called one degree (1°). So, a straight angle is 180° and complete angle is 360°. Each degree is further divided into 60 equal parts and each part is called one minute (1'). Each minute again has 60 equal parts, each part being called one second (1).

1. Thus, 1 right angle = 90°; 1° = 60; 1° = 60°. e.g., 40.32° = 40°(0.32 * 60)’ = 40°19.2’ = 40°19’(0.2 *60) = 40°19 -12' 2. In circular system, the unit of measurement is radians. One radian is defined as the angle subtended at the center of a circle by an arc of length equal to the radius of that circle. It is written as 1c.

Chapter 4 Principle of Mathematical Induction Principle of Mathematical Induction deals with topics such as the process of proving the induction its application in natural numbers as the least inductive subset of real numbers. Numerical related to the Principle of Mathematical Induction.

Chapter 5 Complex Numbers and Quadratic Equations Very often we come across many equations involving several powers of one variable. If the indices of all these powers are integers then the equation is called a polynomial equation. If the highest index of a polynomial equation in one variable is two, then it is a quadratic equation. A quadratic equation is a second degree polynomial in x usually equated to zero. In other ‘words, for an equation to be a quadratic, the coefficient of x2 should not be zero and the coefficients of any higher power of x should be 0.

Roots of the equation- Just as a first degree equation in x has one value of x satisfying the equation, a quadratic equation in x has two values of x that satisfy the equation. The values of x that satisfy the equation are called the roots of the equation. These roots may be real or complex.

Chapter 6 Linear Inequalities In earlier classes, we have studied equations in one variable and two variables and also solved some statement problems by translating them in the form of equations.

Now a natural question arises: ‘Is it always possible to translate a statement problem in the form of an equation? For example, the height of all the students in your class is less than 160 cm.

Your classroom can occupy atmost 60 tables or chairs or both. Here we get certain statements involving a sign ‘<’ (less than), ‘>’ (greater than), (less than or equal) and (greater than or equal) which are known as inequalities. In this Chapter, we will study linear inequalities in one and two variables. The study of inequalities is very useful in solving problems in the field of science, mathematics, statistics, optimisation problems, economics, psychology, etc.

Chapter 7 Permutations and Combinations In real life we are often encountered with problems of counting. Many a times the number of ways of happening of an event is so large that we can not count it on

our hands. Permutation and Combinations are techniques to simplify the process of counting and are very useful when the number of ways of happening of some event are very large.

The Sum Rule- Suppose a work A can occur in m ways and B can occur in n ways and both cannot occur simultaneously. Then A or B (at least one of them) can occur in (m + n) ways. This rule is also applicable for two or more exclusive events.

The Product rule- Suppose there are two works A and B. Let A can occur in m ways and B in n ways. Suppose that the ways for A and B are not related in the sense that B occur in n ways regardless the outcome of A. Then both A and B can occur in mn ways.

For example, let there be two questions A and B which can be solved by two methods and 3 methods respectively. Then both A and B can occur in 2 x 3 = 6 ways. The above rules are very useful and many problems of this chapter can be solved by using these fundamental concepts without using any formula.

Chapter 8 Binomial Theorem Binomial Theorem was introduced by Newton for the purpose of calculating or approximating expansion of two terms raised to any power.

Binomial Expression: Algebraic expressions which have two terms are called Binomial Expressions.

Binomial Expansions: Binomials when raised to different powers are called Binomial Expansions.

Binomial Index: It is the power to which a binomial is raised to give a Binomial Expansion.In this chapter, we are considering only positive integral index.

Coefficient: The constant or the number associated with each term of a binomial expansion is known as the coefficient NCERT Solutions for Class 11 Maths Chapter 8 Binomial Theorem Exercises Exercise 8.1 Exercise 8.2 Miscellaneous Exercise

Chapter 13 Limits and Derivatives The idea of limits is one of the basic concepts that distinguishes calculus from the remaining branches of mathematics. Limits are used to check the behaviour of functions close to certain points. This use paves the way to define continuity and differentiability of functions which are extremely important concepts to analyse functions.

We also introduce derivatives in this lesson and discuss their geometrical significance. Problems involving the concepts of limit, continuity and differentiability simultaneously are very common, which are explained elaborately in this lesson.

Limit and continuity of a function, limit and continuity of the sum, difference, product and quotient of two functions, L’Hospital rule of evaluation of limits of functions, continuity of composite functions, intermediate value property of continuous functions.
