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:
“In time your relatives will come to accept the idea that a career is as important to you as your family. Of course, in time the polar ice cap will melt.”
—Barbara Dale (b. 1940)
“The inhabitants of earth behold commonly but the dark and shadowy under side of heaven’s pavement; it is only when seen at a favorable angle in the horizon, morning or evening, that some faint streaks of the rich lining of the clouds are revealed.”
—Henry David Thoreau (1817–1862)
