Sin

Returns the sine of an angle (in radians).

Built-in Function handler

Syntax:

sin(<angleInRadians>)

Examples:

the sin of -pi/2 -- returns -1

sin(the startAngle of graphic "Pointer")

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:

• angleInRadians:
• angle:A positive or negative number, or an expression that evaluates to anumber.
• Returns: The sin function returns a number between -1 and 1.
