What 15 concepts are covered in the Ordered Pair Calculator?
- cartesian
- a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length
- coordinates
- A set of values that show an exact position
- cos
- cos(θ) is the ratio of the adjacent side of angle θ to the hypotenuse
- degree
- A unit of angle measurement, or a unit of temperature measurement
- ordered pair
- A pair of numbers signifying the location of a point
(x, y) - point
- an exact location in the space, and has no length, width, or thickness
- polar
- a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction
- quadrant
- 1 of 4 sections on the Cartesian graph. Quadrant I: (x, y), Quadrant II (-x, y), Quadrant III, (-x, -y), Quadrant IV (x, -y)
