Does the thought of Maths strike fear in your heart? Sequentially introducing chapters and concepts according to the standards of the latest CBSE syllabus, the NCERT Maths Book Class 9 PDF for free is a must-have for students who are appearing for their Class 9 final exams or for anyone who wants a quick refresher of high school mathematical concepts. You may have heard this saying, but the concept has stood true beyond the tests of time. Maths has brought revolutionary innovations and has impacted the fields of other core Sciences like Physics and Chemistry. It is the language of logic, and by studying it extensively, you learn how to problem-solve better and master the art of thinking abstractly. Our NCERT Maths PDFs will not only boost your confidence by giving you a quick refresher and overview of key concepts covered in the syllabus but also prepare you for any upcoming competitive exams. The IIT and JEE which are two of the most popular national competitive tests even base their question paper patterns from excerpts contained in NCERT textbooks, which makes studying these all the more important for any student who is seriously aspiring to crack engineering or college-level entrance tests.
Being a very precise subject, it can actually be a very easy subject to understand when the basics are integrated firmly. So how does one go about changing this fear of a tough subject and give students the resources to improve their mathematics knowledge? The RD Sharma class 9 maths book solutions are very thorough.
There are detailed solutions that cover the core principles and theories — important formulas and fundamentals that will help students solve all kinds of problems. Algebra, arithmetic, and geometry are full-fledged subjects in themselves and balancing the different topics along with other subjects can sometimes be difficult. The RD Sharma mathematics class 9 solutions will go a long way in helping students learn, and they are free.
But that is not all — online lessons in the core science subjects are now available on our online learning platform to ensure that students are able to keep up with the competition.
As technology improves, teaching methods need to change accordingly. Nowadays, young students spend a lot of time on gadgets and they take in a lot of information on the internet. At Vedantu we aim to ensure that the time children spend with gadgets helps them in their education. Apart from resources like the RD Sharma class 9 solutions free download, we offer a thorough and well-planned online lessons in the core science subjects.
These lessons provide all the benefits of home tutoring at a much lower cost.
It offers students a comprehensive learning experience delivered via a platform that fits naturally into their daily routine.
Let us explore the many benefits of online classes delivered by our team. Tuitions are an important part of school preparations now. Tuitions provide a more customised approach compared to school classrooms where teachers have to attend to very large groups. At the same time, getting hold of good tutors has become a challenge for many parents nowadays. Home tutors are expensive and scheduling with them can be impossible if they are in high demand.
Group-tuitions can have their own disadvantages. In large cities, students already have to spend a lot of time in commuting. Pressure can be one of the main reasons why students fail to grasp concepts — but our lessons allow more time for students, reducing the pressure.
Students get to learn at their own pace - this is very important when they are learning a tough subject. The one-on-one style of learning ensures that all the attention is on the student and there are no distractions. RD Sharma is considered the best preparation guide book for boards by academicians all across the country.
Following are the chapters that this study material covers.
The number system is a foundational concept, essential to progress with the rest of the class 9 math. It also covers the method of rationalising the denominator, a handy technique indispensable for solving complex calculations further in the syllabus. Exponents, also called Powers or Indices, are a requisite concept for algebra.
This chapter provides concepts on the representation of a number in exponent form. The powers or exponents of real numbers follow the same laws as that of rational numbers. Students will be able to solve simplification problems involving powers with the product law, quotient law, and power law. An important concept for solving complex calculations without the help of a calculator, rationalisation helps you to convert a difficult-to-divide fraction into a simpler form.
Solving problems involving the same will help you to solidify these concepts. Algebraic identities offer a shortcut to solving some of the cumbersome and lengthy problems. An algebraic identity is an equality that holds true for any value of the variables in the entire expression.
Factorisation is the opposite of expansion and is an essential concept for class 9 students. It builds on the previous concepts of algebra like identities and exponents. Most algebraic expressions take the form of a polynomial. Learning to factorise a polynomial expression into irreducible factors with coefficients in the same domain is essential.
This chapter teaches you to factorise polynomials with degrees greater than 2 as well, which will help you later on in the class 9 curriculum. The chapter helps you to form the base for geometry. Euclidean geometry is based on axioms and theorems to find out relations between lines, figures and angles in space.
It presents a student with a deductive, comprehensive, and logical approach. You can develop the basics required to progress further into the intricate and intriguing world of geometry. Angles in a geometric figure form various relations with each other. Chapter 8 is all about these relations. Concepts of vertically opposite, complementary and supplementary angles are presented here with clarity. Here, you are introduced to the various types of triangles and the properties of their three angles.
You learn how to figure out the values of unknown angles in a geometry composed by triangles.
Properties like exterior angles, linear pairs, vertically opposite angles, alternate angles, etc. Suppose you see two similar objects and state to a friend that the two are geometrically same. But your friend refuses to believe so. How do you prove it? Studying congruency of triangles provides with an insight on how you can do so.
Here, you build the logic to prove that two triangular 2D bodies are a replica of each other, using Euclidean theorems. Named after Rene Descartes, this branch of mathematics that combines geometry with algebra is called Cartesian coordinate geometry. Plotting points in planes with its coordinates and notations is an essential concept covered in this chapter.
Line equations and Apollonius theorems are included as well. Useful in finding out the area of any triangle where only the length of its sides is given, Herons formula is an essential tool to learn.
Further, the chapter discusses the application of this formula to find areas of quadrilaterals. With the concept of the equation of a straight line, one can solve many other simple real-life problems. Linear equations are an essential tool to do the same. In this chapter, a student learns to present the geometric representation of various straight line equations.
A quadrilateral is a polygon with four edges and four vertices. Here, you learn about the various properties of a quadrilateral and the relation between its angles. After developing the concept of convex and concave triangles, you get to solve problems involving a variety of quadrilaterals with unknown values of edges. Formulae of area and volumes of different quadrilaterals are also introduced here. This chapter covers the formulae and methods of calculating the areas of various triangles and other parallelograms like rhombus and trapezium.
One also learns their application by solving problems involving circles with other inscribed geometrical figures. In this chapter, you acquire the skills to construct geometric figures only using a scale and a compass. You learn to construct various angles, bisect lines, inscribe triangles into figures and do much more.
An easy yet scoring chapter, practising the problems here can lead you to get better grades tomorrow. A right circular cylinder is a commonly occurring geometrical figure in many other areas of science like physics and biology. So, you need to learn the ways of measuring its dimensions. That is what you learn in this chapter. Here, a student learns to solve problems involving volume and surface area of a right circular cone.
Learning the formulas for volumes of spheres is a part of the entire curriculum. The chapter falls under the topic of analytical geometry. Statistics is the science of collection, presentation, analysis and interpretation of numerical data.
Here, you are introduced to the basic concepts like primary and secondary data, discrete and continuous frequency distribution, etc. They offer a visual representation of statistical data. In this chapter, you learn about the different measures of central tendencies such as the mean, median and mode.
With these measures, you can identify the location of maximum number values in a distribution. Here, one understands the essential concepts like different types of events mutually exclusive, complementary, equally likely, etc. One also learns the theorems of compound probability, and other axioms and their application in solving complex problems.
