Syntax
Cos(number)
The number argument can be any valid numeric expression that expresses an angle in radians.
Remarks
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:
related toDim MyAngle, MySecant
MyAngle = 1.3 ' Define angle in radians.
MySecant = 1 / Cos(MyAngle) ' Calculate secant.
