VBScript Cos Function

Returns the cosine of an angle.

Syntax: VBScript Cos Function

Cos(number)

Arguments: VBScript Cos Function

number

Any valid numeric expression that expresses an angle in radians.

Remarks: VBScript Cos Function

The Cos function takes an angle 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. The result lies in the range -1 to 1.

To convert degrees to radians, multiply degrees by pi/180. To convert radians to degrees, multiply radians by 180/pi.

The following example uses the Cos function to return the cosine of an angle:

Dim MyAngle, MySecant

MyAngle = 1.3                 ' Define angle in radians.

MySecant = 1 / Cos(MyAngle)   ' Calculate secant.
