# Syntax

the sin of angleInRadians

# Params

- angleInRadians : 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")

# 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
