# Sin Function

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

## पैरामीटर

Number: Numeric expression that defines the angle in radians that you want to calculate the sine 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 approximately 3.141593.

## उदाहरण:

    ' 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))
