Class 9th Chapter 1: Number Systems
This chapter introduces the concept of real numbers and their properties. It includes rational and irrational numbers, laws of exponents for real numbers, and the representation of numbers on the number line. Students also learn about the classification of numbers and operations involving different types of numbers, including the concept of surds and decimal expansions.
Class 9 Maths Chapter 2: Polynomials
This is the second chapter in the Class 9 Maths syllabus. It introduces the concept of polynomials in one variable, including terms, degrees, and coefficients. The chapter covers types of polynomials (linear, quadratic, cubic), operations on polynomials (addition, subtraction, multiplication), and the use of identities like ( ๐ + ๐ ) 2 (a+b) 2 , ( ๐ โ ๐ ) 2 (aโb) 2 , and ๐ 2 โ ๐ 2 a 2 โb 2 . Students also learn to factor polynomials using common techniques and algebraic identities.
Class 9th Maths Coordinate Geometry
This is the third chapter in the Class 9 Maths syllabus. It introduces the Cartesian system to locate points in a plane. Students learn about the coordinate axes (x-axis and y-axis), the origin, quadrants, and how to plot and name points in the coordinate plane. The chapter builds the basic understanding of geometry using algebra and is foundational for studying graphs, geometry, and trigonometry in higher classes.
