This is the very first chapter in RD Sharma Solutions for Class 11th Maths. It deals with sets. Sets are defined as a collection of well-defined elements which does not change from person to person. A set can be represented by a capital letter. The number of objects in the finite set is termed to be the cardinal number of a set. In this chapter, students learn about the usage of sets and the different types of sets based on their elements. This chapter holds value as the topics discussed in it will be applied in the following chapters.
'Relation' in mathematics is termed as the relationship between two or more sets of values. For example, if we consider both x and y as two sets of ordered pairs, and set x has relation with set y, then the values present in the set x are considered the domain while y is called range. After understanding these concepts, students are exposed to exercise problems to excel in this topic. These help us crack problems related to the relation between the given set of elements and their usage.
Chapter 3 deals with the function as a correspondence between two sets related to the other. Moreover, a function is best described as a relation. It is between a set of inputs that have definite outputs such that each input is related to exactly one output. The students are engaged with numerical problems in order to solidify their knowledge of this concept. So, this is a summary of what this chapter is going to talk about.
In the previous years, students have studied some of the basics of trigonometry, a branch in mathematics that deals with the angles and sides of a triangle. In RD Sharma Solutions for Class 11 Maths Chapter 4- Measurement of Angles, students can learn the relation between degrees, radians and real numbers. These are some of the key concepts that are covered in this chapter. Along with this, solution problems are also taught to the students using detailed explanations of each solution.
This chapter talks exclusively about the definitions of trigonometric ratios to any given angle that is then termed as a trigonometric function. Trigonometric functions are described as circular functions that can be easily defined in terms of the functions of an angle of any triangle. Following are the basic trigonometric functions; sine, cosine, tangent, cotangent, secant and cosecant.
The trigonometric functions are classified as periodic functions. In this chapter, the students study the graphs of these trigonometric functions subjected to their periods. Since these functions are periodic, there is a clear repetition seen in the values obtained by these functions. To provide more knowledge on this topic, students are exposed to some of the basic exercise problems and can also solve them on their own with the help of the support provided by our experts.
'Trigonometric functions' include trigonometric ratios and compound and multiple angles used to get consistent results. In RD Sharma Solutions for Class 11 Maths Chapter 7, students learn some of the formulae that express trigonometric functions' values while performing addition or subtraction of two real numbers. Additionally, students also get to study compound angles. A compound angle is termed the sum of two or more angles.
In this chapter, students are provided with the opportunity to study about two sets of transformation formulae. Formulae transform the product into a sum or difference, and Formulae transform the sum or difference into a product. These are the fundamental concepts mentioned in this chapter, so one should have a thorough acquaintance with these formulae. The RD Sharma Solutions for Class 11 Maths Chapter 8 consists of two unique exercises.
Chapter 9-Trigonometric ratios of Multiple and Sub-Multiple Angles deal with the formula that expresses trigonometric functions at two, three or multiple times of the value A or half, one-third (sub-multiple) of the value of the angle A.

This chapter is based on the intricacies of trigonometric equations. Trigonometric equations are the equations that are formed by using trigonometric values of various unknown angles. They can be expressed as the ratios of sin, cot, cos, tan, sec, cosec. All possible values that possess the ability to satisfy the given trigonometric equations are considered the given trigonometric equation solutions.
The RD Sharma Solutions for Class 11 Maths Chapter 12 deals with the topic called mathematical induction. It is a mathematical technique that is mainly used in proving a statement, a theorem or a formula and is true for every natural number. This method involves two basic steps, namely, the Base step and the Inductive step. The Base step is mainly used for proving whether the statement is true for the initial value. The inductive step proves that if the statement is true for the nth iteration, it is also true for the (n + 1)th iteration.
Chapter 13-Complex Numbers deals with the concept that complex numbers are nothing but the simple combination of real numbers and imaginary numbers. Other important topics in the chapter include the introduction of 'iota', the operations based on it, imaginary quantities, cube root of unity, division, multiplication and modulus of complex numbers. After understanding the basics, students solve the exercise problems, which will help them in their exams.
In the previous chapters, students have learnt about quadratic equations with real roots and real coefficients. Meanwhile, with the help of Chapter 14-Quadratic Equations, students get to learn some other important concepts such as quadratic equations with real coefficients and complex roots. With the help of materials provided by our experts, students can get a clear idea of how to solve the problems based on the concepts discussed in this chapter.
The main concepts covered in Chapter 15-Linear Inequations are the linear inequations in one and two variables. Linear inequalities are equations where two expressions or values are compared using inequality signs such as <, >, ≤, ≥. The knowledge acquired from this chapter will help the students to solve problems in many different domains, namely Mathematics, Science, Engineering and Linear Programming.
Permutations are nothing but the process of ordering a list of objects. For instance, arranging 10 people in a line is considered equivalent to finding permutations of 10 objects. In RD Sharma Solutions for Class 11 Maths Chapter 16, the term and notation of factorial are introduced. The fundamental concepts explained in this chapter include factorial, fundamental principles of counting, permutations, permutations of objects, permutations under certain conditions etc.
The main concepts discussed in RD Sharma Solutions for Class 11 Maths Chapter 17 are Combinations, Properties of Combinations, practical problems of combinations, and mixed problems on both combinations and permutations. Combinations can be described as the different selections made by considering either some or all of the number of objects irrespective of their arrangements. Therefore, the concepts in this chapter need to be understood thoroughly as they find applications in the chapters that follow.
Chapter 18-Binomial Theorem introduces a new concept related to the chapters that dealt with permutation and combination. The binomial theorem can be defined as the method of expanding an expression that has been raised to any finite power. Binomial expressions can sometimes be very lengthy and tedious to calculate. So, using the binomial theorem makes it easier to calculate a binomial expression raised to a very large power. Thus, it is considered a powerful expansion tool that applies concepts like algebra, probability, etc. In this chapter, students learn concepts like the Binomial theorem and some of its important conclusions and general and middle terms in a binomial expansion.
Arithmetic progression is considered a sequence in which the difference between the term and the previous term is constant. For instance, the series of natural numbers: 10, 20, 30, 40, 50,… is termed as an AP, which has a common difference between two successive terms equal to 10. The chapter deals with concepts such as the general form of an arithmetic series, the nth term of an arithmetic series and the sum of n terms. In addition, there are questions based on the difference of the sum of two different arithmetic series. Apart from just grasping the concepts, students also get to solve the practice problems and exercise problems to further enhance their knowledge.
Before diving deep into this topic, students are taught what exactly a geometric progression is. The Geometric progression is defined as follows: it is a sequence of terms where each succeeding term is being generated by multiplying the preceding terms with a constant value. GP denotes the sequence, and the multiplying term is known as the common ratio. In RD Sharma Solutions for Class 11 Maths Chapter 20, students also get exposed to exercise questions based on the general form of a geometric progression, common ratio, nth term of the GP, the sum of n terms of a GP. The exercises and the solutions provided get the students to solve the problems on their own after mastering this basic concept.
