# Sin Function

각도의 사인을 구합니다. 각도는 라디안으로 지정됩니다. 결과는 -1에서 1 사이입니다.

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

### Syntax:

    Sin (Number As Double) As Double

### Return value:

Double

### Parameters:

Number: 사인을 계산할 각도를 라디안으로 지정하는 숫자 식입니다.

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.

### Example:

    REM In this example, the following entry is possible for a right-angled triangle:
    REM The side opposite the angle and the angle (in degrees) to calculate the length of the hypotenuse:
    Sub ExampleSine
    REM 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$("알파 각도(도 단위) 입력: ","Alpha")
        Print "The length of the hypotenuse is"; (d1 / sin (dAlpha * Pi / 180))
    End Sub
