In geometry, the polar angle may be
- one of the two coordinates of a two-dimensional polar coordinate system;
- one of the three coordinates of a three-dimensional spherical coordinate system; in this case it is also called the zenith.
Famous quotes containing the words polar and/or angle:
“Professor Fate: My apologies. There’s a polar bear in our car.”
—Arthur Ross. Professor Fate (Jack Lemmon)
“I fly in dreams, I know it is my privilege, I do not recall a single situation in dreams when I was unable to fly. To execute every sort of curve and angle with a light impulse, a flying mathematics—that is so distinct a happiness that it has permanently suffused my basic sense of happiness.”
—Friedrich Nietzsche (1844–1900)
