NCERT Solutions for Class 9 Math

There are total fifteen chapters which are divided into six sections, number systems, algebra, coordinate geometry, geometry, mensuration and statistics & probability. In the first part, we will learn about real numbers and their decimal expansion. We will also study how to represent real numbers on number line and laws of exponents for real numbers. The second section is algebra in which we will see polynomials and linear equations and two variables. In the polynomials part, we will study definition of a polynomial in one variable, degree of polynomial, zeroes of polynomials, will recall various algebraic expressions and identities and learn their use in factorization of polynomials. In the another chapter, we will focus on linear equations of the type ax+by+c=0 and learn a linear equation in two variables has infinitely many solutions. The third section is Coordinate geometry in which we will learn about the Cartesian plane, coordinates of a point, names and terms associated with the coordinate plane, notations, plotting points in the plane. The fourth section is geometry in which there are seven chapters. In the first chapter, we will be studying the five postulates of Euclid and learn the relationship between axiom and theorem. The next four chapters only covers important proofs. There are total eight important proofs in these chapters: first, If two lines intersect, vertically opposite angles are equal. Second, The sum of the angles of a triangle is 180°. Third, Two triangles are congruent if any two angles and the included side of one triangle is
equal to any two angles and the included side of the other triangle (ASA Congruence). Fourth, The angles opposite to equal sides of a triangle are equal. Fifth, The diagonal divides a parallelogram into two congruent triangles. Sixth, Parallelograms on the same base and between the same parallels have equal area. Seventh, Equal chords of a circle subtend equal angles at the center and (motivate) its
converse. Eighth, The angle subtended by an arc at the center is double the angle subtended by it at any point on the remaining part of the circle. The last chapter is based on geometrical constructional activities such as bisecting line segments and constructing triangle at given base. The fifth section is Mensuration in which there are two chapters, area and surface areas and volumes. In the first chapter, we will learn to find area of a triangle using Heron's formula and its application in finding the area
of a quadrilateral. In the second chapter, we will find Surface areas and volumes of cubes, cuboids, spheres and right circular cylinders. The sixth and last section consists of two chapters, statistics and probability in which we will study presentation of data and chances of happening of a specific events.

NCERT Solutions for Class 9 Science

There are fifteen chapters that are divided into five sections, Matter- Its nature and behaviour, Organization in the living world, Motion, Force and Work, Our Environment and Food Production. The first section is part of chemistry, the second and last two sections are part of biology while third section form physics part. The first section has four chapters. In the first chapter, matter in our surroundings we will study definition of matter and its characteristics. Matter around us pure deals with the Elements, compounds and mixtures. In Atoms and Molecules chapter we will study the Law of constant proportions, Atomic and molecular masses and Mole concept. The last chapter of first section is Structure of Atom in which we will be studying Electrons, protons and neutrons and terms such as Isotopes and Isobars. The second section consists of four chapters. The fundamental unit of life talks about the cell and its structure and importance. We will study the structure and functions of animal and plant tissues. In Diversity in living organisms chapter, we will learn about the Hierarchy of categories in plants and animals. The last chapter of this section is why do we fall ill in which we will learn the importance of health and various types of disease. The third section has five chapters related to physical science which deals with the Motion, Force and Newton’s laws, Gravitation, Floatation, Work, energy and power and Sound. The fourth section is related to Natural Resources. Last section is about food production.There are two textbooks Beehive and Moments. Beehive comprises a rich variety of reading material which include the literary, cultural and sociological dimensions of texts. The themes range from childhood and adolescence, to disability, talent and achievement, to music, science, and contemporary social and environmental concerns.The book draws on different genres such as story, biography and autobiography, science fiction, humour, travelogue and the one-act play. Moments is a supplementary reader meant for extensive reading. The text comprises the stories of mystery, adventure, courage, growing up, romance, wit and humour.
