Function
Syntax	math.sin( Number ) Where is this used?
Description:
Returns the sine of a number (in radians).
Returns:	Number number
Part of Library:	Math
Realm:

Examples

Description	Gets the sine of 30 radians. This is very different from 30 degrees.
Used on
Code	local angle = math.sin(30)
Output	The variable angle will be set to -0.9880316...

Description	Gets the sine of pi/6 radians. This is equivalent to 30 degrees.
Used on
Code	local angle = math.sin( math.pi / 6 )
Output	The variable angle will be set to 0.5

Description	Get the sine of 30 degrees after having converted it to radians. This would be useful if you are using degrees in your code and want to get the sine of an angle not expressed in radians.
Used on
Code	local angle = math.sin( math.rad(30) )
Output	The variable angle will be set to 0.5. This is the sine of 30 NOT in radians.

Additional Notes

• When the description says returns the sine of a number (in radians), it means the argument passed to the function should be in radians.

• For those of you who don't know what a radian is, a radian is equal to the degree measure of an angle times the quantity pi divided by 180. Put simply, radians = degrees * (pi/180). Use math.rad to convert degrees to radians in your code.
