SIN[edit]

Syntax[edit]

theSine# = SIN(expr)

Description[edit]

Returns the sine of expr, where expr is given in radians. The returned value will be in the range -1 to +1. SIN always returns a double-precision result.

Note[edit]

To find the sine of an angle degAngle which is given in degrees, use the following:

   theSine# = SIN(degAngle * pi# / 180)

where pi# equals 3.14159265359
