The chapter “Linear Inequalities” in NCERT Class 11 Maths helps students understand the concept of inequalities beyond equations. It introduces algebraic solutions of linear inequalities in one variable and their graphical representation on the number line. For two variables, students learn to represent solutions graphically on a coordinate plane using half-planes.
Key topics include rules of inequalities, solving simultaneous linear inequalities, and graphical methods of finding solution sets. The chapter also covers practical applications like problems on inequalities in real-life situations, profit-loss, and optimization.
Step-by-step explanations, solved examples, and exercises in the NCERT book strengthen logical reasoning and analytical skills.
This chapter forms a foundation for higher-level concepts in algebra and is highly useful for Class 11 board exams, JEE, and competitive entrance tests where problem-solving using inequalities is essential.
