Cartesian Coordinate System
Cartesian coordinate system
A system in which the location of a point is given by coordinates that represent its distances from perpendicular lines that intersect at a point called the origin. They are also called rectangular coordinates because it is like we are forming a rectangle.
Cartesian Coordinate System Wikipedia
A cartesian coordinate system also known as rectangular coordinate system can be used to plot points and graph lines.
A cartesian coordinate system in two dimensions also called a rectangular coordinate system or an orthogonal coordinate system is defined by an ordered pair of perpendicular lines axes a single unit of length for both axes and an orientation for each axis. If only one coordinate of three is given to be constant and rest two are. The axes divide the cartesian plane into four quadrants denoted by roman numerals. Unlike other coordinate systems such as spherical coordinates cartesian coordinates specify a unique point for every pair x y or triple x y z of numbers and each coordinate can take on any real value.
The horizontal line is called x axis and vertical the one y axis. In the cartesian coordinate system any point of the space is represented using three. I ii iii iv numbering in a counter clockwise direction the illustration on the left. In mathematics the cartesian coordinate system or rectangular coordinate system is used to determine each pointuniquely in a plane through two numbers usually called the x coordinateand the y coordinateof the point.
What is cartesian coordinate system. The origin is sometimes labeled o and then the axes are called ox and oy. The point 12 5 is 12 units along and 5 units up. Cartesian coordinates using cartesian coordinates we mark a point on a graph by how far along and how far up it is.
The point where the axes meet is the origin of the coordinate system and it represents zero for both axes 0 0. The following is an example of rectangular coordinate system it is basically a set of two number lines the horizontal line is called x axis and the vertical line is called y axis. We choose a point o origin on the line a unit of length and orientation for the line. The cartesian coordinate system for one dimensional space consists of a line.
The orientation chooses which of the two half lines determined by o is the positive and which is negative. Vectors in cartesian. In three dimensional space it has three the x axis y axis and z axis. Constant coordinate surfaces and lines.
The cartesian coordinates of the point at the top of your head would be 4 3 2. A cartesian coordinate system in a plane has two perpendicular lines the x axis and y axis.
