COS(radians)

COS

Returns cosine.

radians

A numeric constant, variable or expression for the angle in radians. p is a constant which represents the ratio of the circumference and radius of a circle. There are 2p radians (or 360 degrees) in a circle.

The COS procedure returns the trigonometric cosine of an angle measured in radians. The cosine is the ratio of the length of the angle's adjacent side divided by the length of the hypotenuse.

Return Data Type:

REAL

Example:

PI        EQUATE(3.1415926535898)  !The approx. value of PI

Rad2Deg   EQUATE(57.295779513082)  !Number of degrees in a radian

Deg2Rad   EQUATE(0.0174532925199)  !Number of radians in a degree

CODE

Angle = 45 * Deg2Rad              !Translate 45 degrees to Radians

CosineAngle = COS(Angle)          !Get the cosine of 45 degree angle
