IN MATH: 1. n. a segment of a curve, often of a circle; the set of all points between and including two specific points of a curve. EX. Arc AB includes the points A and B and all the points lying on the circle between them. 2. a prefix meaning "the angle whose." EX. The Arcsin (.5) is /6, in common numbers 30°. To simplify the expression mentally think "the angle whose sine is .5" Read a complete explanation at arc.htm

IN ENGLISH: 1. n. the band of light sometimes created as electricity passes between electrodes. 2. as defined above.

- Let the computer do angle and arc measure and sector area computation for you at the:
__Computation Page__. - Play with angle and arc measure and sector area at:
__arc length, linear speed, and angular speed info__ - Just see the formulas and rational for arc length, linear speed, and angular speed sat:
__arc__

APPLICATION: See list 260
