Class 9 is the foundation for class 10 and beyond.  The mathematics of class 9 is very important for the students of the entire IIT and other reputed universities after their class 12. If the concepts are not clear, students find it hard to clear their board examinations of class 10 and class 12. The things that are learned till class 8 are applied to more complex concepts and theories in the curriculum of class 9. When students put a huge effort to learn the basic concepts then they would not face any blocks further in the subject ahead.

RD Sharma is one of the greatest mathematical professors mainly followed by the CBSE students for his numerical skills. The best solutions are offered by the Rd Sharma solution book for class 9. It includes the chapters like rationalization, polynomials, lines and angles, and several other concepts which are tricky and complex to understand.

Mathematics is a highly scoring subject but it needs effective practice. Class 9 is very much important as it deals with the new concepts and applications in maths. RD Sharma books are effective as they are based on the latest pattern of syllabus and it follows all the guidelines of the CBSE board.  Referring to these books helps the students to score more marks in maths. 

Importance of RD Sharma solution books

RD Sharma is well known for writing comprehensive explanations for complex concepts and simplifying them in mathematics. The  RD Sharma solutions class 9  helped the students by providing easy solutions to the difficult problems that boosted their scores in maths. Most people are scared of mathematics and they find it difficult to solve the questions. This book provides step-by-step methods to understand and solve the problems. It provides detailed solutions to the problems and makes the students a top-scorer in maths. The best feature which makes it a top-selling book is its user-friendly language.

The curriculum covered by RD Sharma solution book

The RD Sharma book contains 25 chapters. Each includes a concept that is much needed for the learners. Chapter 1 is the number system that introduces the students to the number system. It helps them to know about the real numbers, irrational numbers, and their decimal expansions. It also describes how to represent a decimal number on the line. This chapter helps the students to understand the further concepts easily. Chapter 2 is the continuation of chapter 1 where the real numbers and their operations are understood. There will be certain laws related to exponents and it would provide the students with some problems to solve on their own. 

The third chapter makes us familiar with the concepts of identities and rationalization of the denominator. This book provides a detailed explanation of how to rationalize the denominator and provides the problems to solve based on the concept. Chapter 4 speaks about the algebraic identities and problems based on that. It also includes the concepts such as identification of the square of the trinomial, cube of the binomial, sum, and differences of the cubes. Chapter 5 deals with factoring the algebraic expression such as monomial and polynomial with the help of identities. This will make the students practice with the cubes.

Chapter 6 teaches about the concepts of polynomials in one variable, and zeros of a polynomial. It includes the most important theorems like the remainder theorem and the factor theorem. It provides the students with the problems based on these concepts and theorems. Chapter 7 helps the students to understand Euclid’s geometry. Euclid is the one who established the foundation of understanding the concepts of axioms and postulates. It has certain definitions and describes the five famous postulates.

Chapter 8 is all about the lines and angles. It gives the basic terms and definitions about the lines and angles, intersecting and non-intersecting lines, pair of angles, parallel lines, transversal lines which are parallel to the same, and angle sum property of the triangle. Chapter 9 deals with the properties, concepts, and theorems of triangles, and the inequality of triangles. It provides the students with problems to solve based on this concept. Chapter 10 is the continuation of chapter 9. It is all about the congruent triangles, the criteria behind the congruence of the triangles, axioms, and theorems based on these concepts.  

Chapter 11 teaches in detail about the cartesian system and also about how to plot a point in a plane when two coordinates are given. This is another chapter that strengthens the base of the concepts. Chapter 12 makes the students learn about Heron’s formula to calculate the area of the triangle and quadrilateral triangle. It provides the application problems to solve with. Chapter 13 is about the linear equations of two variables. This makes the students familiar with the basics, solutions of linear equations, and graphs with parallel X and Y-axis. Chapter 14 is all about the quadrilateral triangles, types, properties, and the mid-point theorem. Chapter 15 helps to calculate the area of the triangle and parallelogram with the base and height.

Chapter 16 is related to the concepts of circles, angles that a chord substance to the points, perpendicular from the center to the chords, circle through three points, equal chords and their distance from the center, and angle of an arc. chapter 17 is all about the construction of the circle, a perpendicular bisector of a line segment, and different angles. Chapter 18 deals with the calculation of the volume and surface area of a cube and cuboid. It provides the application problems for the same. Chapter 19 deals with the calculation of the volume and surface area of a right circular cylinder. Chapter 20 is about a new concept of the right circular cone. It helps in the calculation of the volume and surface area of a right circular cone. Chapter 21 is the continuation of chapter 20. Chapter 22 helps the students to understand the concepts of data collection and the tabular representation of the data. Chapter 23 deals with the graphical representation of the statistical data. Chapter 24 is the extension of chapters 22 and 23. Chapter 25 deals with the concepts of probability.
