What is the coordinates of a point on the number line?
the distance from the origin
Which expression gives the distance from the origin to a point with coordinate x y?
Distance = sqrt(x2 + y2)
That does the x-coordinate of an ordered pair specifies?
It is the distance to the right of the origin, which is the point whose coordinates are (0,0).
In cartesian coordinate system what is the coordinates?
The coordinates of a point in the n-space are ordered sets of n numbers, each of which measures the distance of the point from the origin along the n-axes in a given order.
What is the pole of polar coordinates?
That is the origin O, from which all angles and distances to the point are measured, instead of measuring distance from the axes. In bipolar coordinates, there are two poles, from which angles are both measured to determine the distance.
What are the x and y coordinates of a point?
The x coordinate is the distance to the right (East) from the origin while the y coordinate is the distance up the page (North).
What are the characteristics of a coordinate plane?
It is a plane surface with an origin and a pair of orthogonal axes. The location of any point in the plane is given by an ordered pair of coordinates: the abscissa (distance to the right of the origin) and the ordinate (distance in the vertical direction from the origin).
A fixed point from which coordinates are measured?
The Origin.
How do you give the coordinates of a point that lies in the interior of the angle?
The coordinates of a point are in reference to the origin, the point with coordinates (0,0). The existence (or otherwise) of an angle are irrelevant.
When using latitude and longitude coordinates where is the point of origin?
0,0 is the origin
What is used to locate point in the plane?
Coordinates. These may be Cartesian - ie distance from the origin in mutually perpendicular (orthogonal) directions. Or they may be polar. Polar coordinates consists of the length of the line joining the point to the origin together with the angles that the line makes with the various principal planes (or hyperplanes).
What are the types of coordinate system?
There are two main types: Cartesian coordinates and Polar coordinates.In n-dimensional Cartesian coordinates there are n axes which are [usually] orthogonal and which meet at a single point called the origin. The coordinates of any point in the n-space are defined by the ordered n-tuple whose terms refer to the distances of the point, from the origin, along each of the axes.In n-dimensional Polar coordinates, the point is located using its distance from the origin and the angles that this radial line makes with specified lines and planes.
