polar distance
41polar coordinates — n. a pair of numbers that locate a point in a plane: one is the distance of the point from a fixed point on a fixed line, and the other is the angle made by the fixed line with the line connecting the two points …
42Polar coordinate system — Points in the polar coordinate system with pole O and polar axis L. In green, the point with radial coordinate 3 and angular coordinate 60 …
43Polar Challenge — The Polar Challenge is a competitive, 350 nautical mile (650 kilometre) team race taking place in the Arctic, to the 1996 location of the Magnetic North Pole and beyond. The race runs between mid April and mid May each year, taking teams… …
44Polar curve (aviation) — A polar curve is a graph of the rate of sink of an aircraft, often a glider, versus its horizontal speed.Measuring a glider s performanceKnowing the best speed to fly is important in exploiting the performance of a glider. Two of the key measures …

46Polar decomposition — In mathematics, particularly in linear algebra and functional analysis, the polar decomposition of a matrix or linear operator is a factorization analogous to the polar form of a nonzero complex number z where r is the absolute value of z (a… …
47Polar region — Earth s polar regions are the areas of the globe surrounding the poles also known as frigid zones. The North Pole and South Pole being the centers, these regions are dominated by the polar ice caps, resting respectively on the Arctic Ocean and… …
48polar ecosystem — Introduction complex of living organisms in polar regions such as polar barrens and tundra. Polar barrens and tundra are found at high latitudes on land surfaces not covered by perpetual ice and snow. These areas lying beyond the tree line …
49polar coordinates — Math. a system of coordinates for locating a point in a plane by the length of its radius vector and the angle this vector makes with the polar axis (polar angle). [1810 20] * * * system of locating points in a plane with reference to a… …
50Polar orbit — A polar orbit is an orbit in which a satellite passes above or nearly above both poles of the body (usually a planet such as the Earth, but possibly another body such as the Sun) being orbited on each revolution. It therefore has an inclination… …
