Cos Function/text/sbasic/shared/03080102.xhpCos functionCos FunctionCalculates 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/HypotenuseSyntax:Cos (Number)Return value:DoubleParameters:Number: Numeric expression that specifies an angle in radians that you want to calculate the cosine for.To convert degrees to radians, multiply degrees by pi/180. To convert radians to degrees, multiply radians by 180/pi.degree=(radian*180)/piradian=(degree*pi)/180Pi is here the fixed circle constant with the rounded value 3.14159...Example:' 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' rounded Pi = 3.14159Dim 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
