Important Topics for RS Aggarwal Solutions for Class 11 Chapter 7

Inequality 

Any two real numbers or the algebraic expressions that are related to any symbol like <,>, etc. forms an inequality. 

For example

3<5- a numerical inequality

x<5 – a literal inequality

3<5<7  is an example of double inequality. 

Types of Inequalities

Numerical Inequality:

  • Relationship between numbers. For eg; 3<5
  • Literal or Variable Inequality: Relation between variable and number. For eg; x < 5
  • Double Inequality: Relationship from two sides. For eg; 2<x<5
  • Strict Inequality
  • Slack inequalities
  • Linear Inequalities in two variable
  • Quadratic inequalities

Linear Inequality in two Variables

A linear inequality consists of a solution set that consists of a region defining half of the plane

Some important points covered under Graphical representation of Linear Inequality in Two Variable

  • The region that contains all the solutions of an inequality is called the solution region. 
  • To identify the half-plane that inequality represents, you can take any point (a,b) and check if it satisfies the inequality or not. If it does so, then inequality represents half-plane and you should shade the region that contains the point, otherwise, the inequality represents that half-plane which does not contain the point. 
  • Linear inequalities that contain two variables have infinitely many numbers of the ordered pair solutions, that can be easily graphed by shading the appropriate half of a rectangular coordinate plane. 
  • If you are asked to graph the solution set of inequality of two variables, you need to initially graph the boundary with a solid or dash line based on the type of inequality. 
  • In case of a strict inequality, you can use a dashed line while in case of an inclusive inequality, draw a solid line.
