COS


Returns the cosine of an angle

Syntax:
Usage:
result = Cos( angle )

Parameters:
angle
the angle (in radians)

Return Value:
Returns the cosine of the argument angle as a Double within the range of -1.0 to 1.0.

Description:
The argument number is measured in radians (not degrees).

The value returned by this function is undefined for values of angle with an absolute value of 2 ^ 63 or greater.

Examples:
Const PI As Double = 3.1415926535897932
Dim a As Double
Dim r As Double
Input "Please enter an angle in degrees: ", a
r = a * PI / 180    'Convert the degrees to Radians
Print ""
Print "The cosine of a" ; a; " degree angle is"; Cos ( r )
Sleep

Output:
Please enter an angle in degrees: 30
The cosine of a 30 degree angle Is 0.8660254037844387
