Cos

Using the Cos Function

In this tutorial you will learn how to use the 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.

In this example we will use 1.

The result is 0.54030230586814.

The results using a Query would be

	SELECT Cos(1);
	

In a Form you could set the Default Value of a Textbox to

	=Cos(1)
	

In a Form add a TEXTBOX control and rename it "txtCos", then you could add the following in the Load Event.

	Private Sub Form_Load()
		txtCos = Cos(1)
	End Sub
