|An expression that resolves to a number that expresses an angle in degrees.
The COSH function takes an angle in degrees and returns the ratio of two sides of a right triangle. The ratio is the length of the side adjacent to the angle divided by the length of the hypotenuse. This ratio is in the range of 1 to -1 (inclusive).
The following example uses the COSH function to return the hyperbolic cosine of an angle:
MyAngle = 1.3; ! Define angle in degrees.
PRINT COSH(MyAngle); ! Returns hyperbolic cosine ratio.
