## Chapter 2: Relations

Chapter 2 discusses how to establish a relation or inverse relation between two sets and how to determine whether the relation is a function. Cartesian products of two sets ordered pairs and ordered pair equality are all crucial concepts that are explained thoroughly. The chapter explains what exactly is meant by relations and what are inverse relations.

## Chapter 3: Functions

The Chapter teaches the students about the definition of functions and introduces various functions, such as real-valued functions, polynomial functions, rational functions, modulus functions, signum functions, greatest integer functions, and fractional part functions, in proper logical order.

## Chapter 4: Principle of Mathematical Induction

By using mathematical induction, we can evaluate different formulae. The chapter explains the concepts which are used to determine the feasibility of a formula for any value. First, the formula is checked for a value of one, then for any random value of K and K+1. Finally, if the formula holds value for all the three values, it is considered variable for any number n. Since formulas are one of the most important entities in mathematical and scientific study, it is critical to understand the inductive hypothesis, which assumes the truth of a statement.

## Chapter 5: Complex Numbers and Quadratic Equations

Arithmetic Progression (AP) is one of the most important chapters taught in the course. The chapter holds importance for computational and higher mathematical studies as it forms the basis for various types of sequences and series. The chapter introduces the arithmetic progression in detail, emphasising upon the general form of the arithmetic sequence, finding the n th term from the beginning, the n th term from the end of the series and the sum of n terms of the sequence.

## Chapter 12: Geometric Progression

The Chapter on geometric progression is a continuation of the previous chapter on arithmetic progression. A geometric progression is a series where every new term is obtained by multiplying the previous term with a number. This number is constant throughout the series and is known as the common ratio. The chapter discusses the general form of a GP, the nth term of the progression and the sum of n terms. The formulae for these are also provided in the chapter, and the solution elaborates on the procedures used to solve questions.

## Chapter 13: Some Special Series

The 13 th chapter in RS Aggarwal for class 11th is based on the combination of the previous two chapters.

The chapter also teaches the students about the locus and the family of circles.

## Chapter 22: Parabola

The chapter marks the beginning of the conic section. It is a U-shaped figure which can be defined by the motion of a particle that is at a constant distance from a fixed line (directrix) and a fixed point (focus) at every moment of its motion. It is also the path traced by a projectile. The ratio of the length of the directrix to the moving particle and the length of focus to the moving particle is called eccentricity and is denoted by 'e'. In case of a parabola e = 1.

## Chapter 23: Ellipse

The ellipse is the second topic taught to the students in the conic section in class 11. The figure is defined such that the sum of the distance of the moving particle from the two foci is always constant. The value of eccentricity lies between 0-1. If 'e' becomes zero, the figure converts to a circle, and if it converts to 1, the figure becomes a parabola. The chapter involves the equations of an ellipse of the x and y-axis and questions on various properties associated with it.

## Chapter 24: Hyperbola

This Chapter informs the students about hyperbola, which is the next topic of the conic section. The value of eccentricity for a hyperbola is greater than 1, and the chapter deals with its equations and questions based on its equations, its directrix, latus rectum and its properties.
