In Access, the Cos function returns a double containing the cosine of an angle.

The syntax for the Cos function is:

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.

SQL query

You can also use the Cos function in a query.

SELECT Cos([OwnerId]) AS Expr1 FROM Orders
