In mathematics, the Cartesian coordinate system is used to determine each point uniquely in a plane through two numbers, usually called the x-coordinate and the y-coordinate of the point. To define the coordinates, two perpendicular directed lines (the x-axis or abscissa and the y-axis or ordinate), are specified, as well as the unit length, which is marked off on the two axes .Cartesian coordinate systems are also used in space (where three coordinates are used) and in higher dimensions.
I hope this helps. :)

In a play field you drop a coin you dont know where, unless you have the 'address' of every place in the field. Towards this end of having an address of places throughout the field, you need a 'fixed point of reference' and two' fixed directions', say one East-West direction and another North-South , direction. Now staring from your 'fixed reference point' or 'the origin' as all call it, you can reach any other point only by going some steps in East-West direction and some more steps in North-South direction. Thus the point in question has the address something like (5steps East-West, 4 steps North-South) or, (5,4) in short. Then come the question of 'distance ' between two points A(m,n) and B(p,q), called 'co-ordinates' of the points. Joining the line AB and taking its projections along the East-West direction and the North-South directions, The distance AB is the square root of squares of these projections by Pythagoras theorem. Of course the distance is to be measured in the same scale or in the same unit of steps. This special system of Cartessian coordinates is called rectangular if the fixed directions are perpendicular to each other. If they are inclined to each other at an angle, the coordinate system is still called Cartessian, only formulae develop in a different manner.This contrivance connects Geometry and Algebra , in a way translates geometry into Algebra. You know how Arithmetic was made easy when translated to Algebra. Just in the same manner, Geometry was made easy through Coordinate Geometry. It is the easiest branch of Mathematics I feel personally. The two-direction coordinate system is called Cartessian system , named after its discoverer and developer, Des Cartes. He is also perhaps a great exponent of Western Philosophy. It is said that he discovered Coordinate Geometry ( system of coordinates) while lying in his bed and watching spider fall for its prey in the cobweb, when he was an ailing child.
Instead of keeping a fixed point and two fixed directions for reference, one could keep a fixed point (called origin), a fixed line, only, such as, if you want to reach a particular point, just stand at the origin, look in the direction of the fixed line, turn yourself in the direction of the point in question ( rotate through requiste angle) and straight head towards the point traversing a particular distance. This is called a polar coordinate system, But there is no concession of the number of variables, (r, theta) is the coordinate of the point instead of (x,y); the same two in number. Of course the two coordinate systems can be trnsform into each other easily and there are particular advantages to each one too.An ailing child thought so simple and yet so powerful that without the knowledge, perhaps we cound not have landed on the moon.

The xy axis is called the cartesion plane. So cartesion coordinates are just the x and y values on the xy axis
ex. (4,2) are cartesion coordinates

It's spelled "Cartesian". That was the name of the person who made it popular.
It means using 2 numbers to find a location on a flat plane -- like a flat paper. The first number is usually called "X", and is how far left or right from a starting point. The second number is usually called "Y" and is how far down or up from the starting point.

The cartesian system will specify a point by three coordinates x, y, and z, the axes being mutually perpendicular.

diverse translations of the bible would advise love and charity are synonmus. Examples present day in.1st Corrinthians ch. 13 vs. a million-17 illustrate this many circumstances. i'd take excitement in listening to from a student of the languages utilized in those previous circumstances to make sparkling my wisdom. the story of the "international's Poorest Philanthropist", Gilbert "Harold" Ewing II (myself) is the rationalization for this querry. The " act of grace", or charity, reffered to in the information interview, has posited this question and that i lack the form of training to offer any insights of actual value.

thas we know that the position of an object in space can be determined by a minimum of three coordinates there fore cartesian coordinates represents one of the way of representing the postion of object with respect to defined origin in way of distance from the three mutually prependicular axes.

we know that there r 3 dimentions in space we name them x,y&z &they r perpendicular 2 each other so if we have apoint in space we have 2 analyise this point as(x,y,z) .....&this what we call cartesian coordinate
