Known alternatively as Cartesian coordinates, rectangular coordinates are a way to denote a point in space using two or three values, namely (x, y) or (x, y, z). When converting from cylindrical or polar coordinates to rectangular, one must employ principles of trigonometry. For example, in a 2D plane, 'x' can be calculated as r*cos(θ) and 'y' as r*sin(θ).
