An inequality involve one of the four symbols.
> , ≥ , < or ≤
The following statements illustrate the meaning of each of them.
x > 1 : x is greater than 1.
x ≥ -3 : x is greater than or equal to -3
x < 7 : x is less than 7
x ≤ -9 : x is less than or equal to -9
Inequalities can be represented on a number line , as shown in the following applet.
Note that solid mark(●) , is used to show that this value is included and hollow mark(Ο) is used to show that this value is not include.

Thank you for providing such a nice illustrations. I would like to know how to construct these applets. Can you place provide the Step-By-Step documentation for all applets you have created?
ReplyDeleteThank you for showing interest in my blog AGNI. All these applets are created with GeoGebra. Please download it from http://www.geogebra.org/cms/index.php. GeoGebra requires JAVA please download its latest version from http://java.com/en/download/index.jsp. I have not created step by step documentation of my applets. I can share some of my applets with you , please share your email id.
ReplyDeleteThanks for sharing information about inequality.Online tutoring is very helpful in solving the math problems and to understand the higher section topics.It can be very helpful for beginners because it provide practice and guidance for them.So that they will not face any kind of problem in future regarding further studies.
