Cos Function
Calculates the cosine of an angle. The angle is specified in radians. The result lies between -1 and 1.
Using the angle Alpha, the Cos-Function calculates the ratio of the length of the side that is adjacent to the angle, divided by the length of the hypotenuse in a right-angled triangle.
Cos(Alpha) = Adjacent/Hypotenuse

Number: Numeric expression that specifies an angle in radians that you want to calculate the cosine for.
डिग्री को रेडियन में बदलने के लिए, डिग्री को pi/180 से गुणा करें. रेडियन को डिग्री में बदलने के लिए, रेडियन को 180/pi से गुणा करें.
grad=(radiant*180)/pi
radiant=(grad*pi)/180
Pi is here the fixed circle constant with the rounded value 3.14159...
उदाहरण:
' The following example allows for a right-angled triangle the input of
' secant and angle (in degrees) and calculates the length of the hypotenuse:
Sub ExampleCosinus
REM rounded Pi = 3.14159
Dim d1 As Double, dAngle As Double
d1 = InputBox("Enter the length of the adjacent side: ","Adjacent")
dAngle = InputBox("Enter the angle Alpha (in degrees): ","Alpha")
Print "The length of the hypothenuse is"; (d1 / cos (dAngle * Pi / 180))
End Sub
