|number||An expression that resolves to a number that expresses an angle in degrees.|
The SIN function takes an angle in degrees and returns the ratio of two sides of a right triangle. The ratio is the length of the side opposite the angle divided by the length of the hypotenuse, a value in the range -1 to 1 (inclusive).
To return results in radians, set $OPTIONS RADIANS.
To convert degrees to radians, multiply degrees by pi/180. To convert radians to degrees, multiply radians by 180/pi.
The following example uses the SIN function to return the sine of an angle:
DIM MyAngle MyAngle = 1.3; ! Define angle in degrees. PRINT SIN(MyAngle); ! Return sine in radians.
The following example uses the SIN function to return the cosecant of an angle:
DIM MyAngle, MyCosecant MyAngle = 1.3; ! Define angle in degrees. MyCosecant = 1 / SIN(MyAngle); ! Calculate cosecant. PRINT MyCosecant
