CONVERT CARTESIAN COORDINATES TO POLAR COORDINATE

Image
  In mathematics, a Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a set of numeric points. Cartesian Coordinates is represented by (x,y) . In mathematics, the polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point known as radius and an angle from a reference direction known as theta or simply angle. Polar Coordinates system is represented by (r,θ) . For the negative value of r in polar coordinates, what to do? Watch the given below youtube video to cover it. https://www.youtube.com/watch?v=kNANYzuOUpA Fig: Polar Coordinates Check this website for more knowledge: https://openstax.org/books/calculus-volume-2/pages/7-3-polar-coordinates C++ PROGRAM : DEFINE TWO CLASSES POLAR AND RECTANGLE REPRESENT POINTS IN POLAR AND RECTANGULAR SYSTEM. USE SUITABLE MEMBER FUNCTIONS TO CONVERT FROM ONE SYSTEM TO ANOTHER. WR
