    This question should be closed, because there is no magic word "and quickly!" ... - Harry
  • R = 1 (8 characters needed ...) - Igor
  • @Qwertiy - why did you leave c ++? - Igor
  • @Igor thanks, but what are the other 2 parameters equal, such as zenith and azimuth angles? - user513323
  • @ user513323 anything - in its own domain. By the way, the zenith angle ( j ) varies from -90 to 90 degrees. - Igor

Well, since the formulas result in an unbiased sphere

then in spherical coordinates enter image description here it turns out simply: enter image description here

But the " three-dimensional sphere in the Cartesian plane " is cool ... :)
