Returns the sine of an angle. The angle is specified in radians. The result lies between -1 and 1.

Using the angle Alpha, the Sin function returns the ratio of the length of the opposite side of an angle to the length of the hypotenuse in a right-angled triangle.

Sin(Alpha) = side opposite the angle/hypotenuse

```
Sin (Number As Double) As Double
```

Double

Number: Numeric expression that defines the angle in radians that you want to calculate the sine for.

To convert degrees to radians, multiply degrees by Pi/180, and to convert radians to degrees, multiply radians by 180/Pi.

degrees=(radians*180)/Pi

radians=(degrees*Pi)/180

Pi is approximately 3.141593.

```
' In this example, the following entry is possible for a right-angled triangle:
' The side opposite the angle and the angle (in degrees) to calculate the length of the hypotenuse:
Sub ExampleSine
' Pi = 3.1415926 is a predefined variable
Dim d1 As Double
Dim dAlpha As Double
d1 = InputBox("Enter the length of the opposite side: ","Opposite Side")
dAlpha = InputBox("Enter the angle Alpha (in degrees): ","Alpha")
Print "The length of the hypotenuse is"; (d1 / sin (dAlpha * Pi / 180))
End Sub
