7. The Cartesian coordinates of a point are (x,y), while its polar coordinates are (r,0). Determine the polar coordinates of the following points in terms of r and 0: а) (-х, у) b) (-2х, — 2у) с) (3х, — Зу)

Coordinate geometry, also known as analytic geometry or Cartesian geometry in classical mathematics, is a type of geometry that is studied using a coordinate system. Coordinate geometry is a branch of mathematics that describes the position of points on …
