Name: sin

Type: function

Syntax: the sin of <angleInRadians> 

Syntax: sin(<angleInRadians>)

Summary: <return|Returns> the sine of an angle (in <radian|radians>).

Introduced: 1.0

OS: mac,windows,linux,ios,android

Platforms: desktop,server,web,mobile

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

Example:
sin(the startAngle of graphic "Pointer")

Parameters:
angleInRadians: 
angle: A positive or negative number, or an expression that evaluates to a number.

Returns: The <sin> <function> <return|returns> a number between -1 and 1.

Description:
Use the <sin> <function> to find the sine of an angle.

The <sin> <function> repeats every 2*pi <radian|radians>:
  sin(x) = sin(x + 2 * pi)
for any value of x.

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

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