SIN()
FUNCTION: sin(<number>[, <units>])
Returns the sine of <number> where <number> is expressed in <units>. <units> may be 'radians', 'degrees', or 'gradians' or just the first letter of any of these. By default, <units> is radians.
In a circle, there are 2*pi() radians, 360 degrees, and 400 gradians.
Examples: > say sin(270,d) You say, "-1" > say sin(fdiv(pi(),2)) You say, "1" > say sin(fdiv(pi(),4)) You say, "0.707107" > say sin(fdiv(pi(),6)) You say, "0.5"
