Question

Explain cartesian co-ordinate system and cartesian co-ordinate plane

Answer 1

A Cartesian coordinate system is a co-ordinate system that specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular directed lines, measured in the same unit of length.

A Cartesian plane (named after French mathematician Rene Descartes, who formalized its use in mathematics) is defined by two perpendicular number lines: the X-X' axis which is horizontal, and the Y-Y' axis which is vertical. Using these axes, we can describe any point in the plane using an ordered pair of numbers.

Answer 2

Step-by-step explanation:

Answer:

To convert from Polar Coordinates (r,θ) to Cartesian Coordinates (x,y) :

x = r × cos( θ )

y = r × sin( θ )
