Get Sine Method

The Get Sine method returns the sine of an angle specified in radians. The return value is between -1 and 1. You specify the angle in radians as a positive or negative number. To convert degrees to radians, this method multiplies degrees by (PI/180). The value of PI is 3.14159.

For information on how this method handles the data type, see How Some Math Methods Handle the Data Type.

Sin(number)

The following table describes the arguments that you can use with this method.

Argument	Description
number	A numeric expression that contains a number that represents the size of an angle in radians.

Example

The following example finds the height of a building, given the length of the roof and the roof pitch:

Sub Button_Click
   Dim height, rooflength, pitch, msgtext As String
   Const PI = 3.14159
   Const conversion = PI/180
   pitch = 35
   pitch = pitch * conversion
   rooflength = 75
   height = Sin(pitch) * rooflength
   msgtext = "The height of the building is " 
   msgtext = msgtext & Format(height, "##.##") & " feet."
End Sub
