Cos ( number )

The argument number can be any valid numeric expression that expresses an angle in radians. 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.

Cos(15)    returns -0,759687912858821 
Cos (2)    returns -0,416146836547142

VBA Code

Dim MyNumber 
MyNumber = Cos(2.5) 

This example uses the Cos function to return the cosine of an angle. Now the MyNumber variable would contain the value -0.80708818.

You can also use the Cos function in a query.

SELECT Cos([OwnerId]) AS Expr1
