sin

Type

function

Summary

Returns the sine of an angle (in radians).

Syntax

the sin of <angleInRadians>

sin(<angleInRadians>)

Description

Use the sin function to find the sine of an angle.

The sin function repeats every 2*pi radians:

    sin(x) = sin(x + 2 * pi)

for any value of x.

The sin function requires its input to be in radians. To provide an angle in degrees, use the following custom function:

    function sinInDegrees angleInDegrees
        return sin(angleInDegrees * pi / 180)
    end sinInDegrees

Parameters

Name	Type	Description
angleInRadians	number	A positive or negative number, or an expression that evaluates to a number.

Examples

put the sin of (-pi/2) -- returns -1

put sin(the startAngle of graphic "Pointer")
