SIN
Returns the sine of an angle.
Synopsis
SIN(number)
Arguments
| number | An expression that resolves to a number that expresses an angle in degrees. |
Description
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.
Examples
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
