For a given acute angle in a right triangle, the ratio: Length of side adjacent to angle X Length of hypotenuse Cross-products The cross-products of the ratios 3/4 and 9/12 are 3 x 12 and 4 x 9. Cube A prism with all square faces. Customary System of Measurement A system for measuring length in inches, feet, yards, miles; capacity in cups, pints, quarts, gallons; weight in temperature in degrees Fahrenheit. Cylinder A solid figure with two circular bases that are parallel and congruent. D's
Cos(q) is the x- coordinate of the point on the unit circle so that the ray connecting the point with the origin makes an angle of q with the positive x- axis. When q is an angle of a right triangle, then cos(q) is the ratio of the adjacent side with the hypotenuse.
Cooperation for Open Systems Interconnection Networking in Europe. European project financed by the European Community (EC) to build a communication network between scientific and industrial entities in Europe. The project ended in 1994.
transform coding: An algorithm or method used by some video codecs to compress digitized motion video images to very low data rates. Relies upon the mathematical transform referred to as the cosine transform. Generally used in intraframe coding.
