d(required; Double or numeric expression)
An angle in radians
A Double data type denoting the cosine of an angle
Takes an angle specified in radians and returns a ratio representing the length of the side adjacent to the angle divided by the length of the hypotenuse
The cosine returned by the function is between -1 and 1.
This is a Shared member, so it can be used without creating any objects.
Dim dblCosine as Double dblCosine = Math.Cos(dblRadians)
To convert degrees to radians, multiply degrees by pi/180.
To convert radians to degrees, multiply radians by 180/pi.
In VB 6, Cos was an intrinsic VB function. In the .NET platform, it is a member of the Math class in the System namespace, and so it is not part of the VB.NET language.
