#### Uses of Cartesian System in 9th Maths Exercise 3.3

The Cartesian coordinate system is a convenient way to allocate a number to locations. According to this, it is a sort of translation in a linguistic sense, between mathematical languages, from geometry talk into algebra talk. It is better for doing algebra and comparing geometry abstractly. Having developed very sophisticated tools for it, so prefer to solve problems in this language. To perform the task of allocation of the number which is also known as plotting the points. Which is another vital process, post solving the equations.

##### Plotting Points in Cartesian System

Plotting points in the coordinate plane is an important skill. It will be introduced in the 3rd last part of the chapter i.e. Exercise 3.3 of Class 9 Maths. According to the NCERT explanation 3.3, until now the chapter only introduces you to the pointing coordinates and their part. Plotting the points is the main work in the coordinate geometry in class 9th Maths. Since, it requires multiple skills, like – positioning, pointing, and drawing. A lot of students like Exercise 3.3 in grade 9 mathematics. Now, reading example with figures given in Exercise 3.3 will help you with further questions.

###### The Real-life applications of the Cartesian plane

There are many real-life application of the Cartesian coordinate system. The Cartesian plane is usually used to represent dimensions. In class 9th math you will study the 2-dimensional figures. It helps in everyday problems related to dimensions, angles, or degree.

For instance – military and defense radar uses 2D and 3D Cartesian plane to represent the location of the enemy. Pilots of aircraft use a gyroscope that represents the angles of the aircraft by representing it on a 3-dimensional plane. Even the screen that you are reading this article is also the use of the Cartesian plane to represent.
