I've been researching the motivation behind the invention of the Cartesian Co-ordinate system. But I was wondering, which coordinate system was the first to be invented? Was it the Spherical Co-ordinate system? And if yes, why was it needed?

  • $\begingroup$ Does it have a name? As in, is it a specific coordinate system. $\endgroup$
