The sine of the complement of an arc or angle. See Illust. of Functions.

The ratio of the length (in a right triangle) of the side adjacent to an acute angle to the length of the hypotenuse

Cosine of Angle: cos A= Adjacent\Hypotenuse.

ratio of the adjacent side to the hypotenuse of a right-angled triangle

(trig) The sine of the complement.

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

For any acute angle in a right triangle, the ratio of the length of the adjacent side, to the length of the hypotenuse.

Cosine (abbreviated cos) is a trigonometric ratio, corresponding to the length of the adjacent side divided by the length of the hypotenuse of the right triangle.

The trigonometric function that is defined as the ratio of the leg adjacent to an angle to the hypotenuse of its right triangle.

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.

The cosine of an angle in a right triangle is equal to the length of the side adjacent to the angle divided by the length of the hypotenuse.
