sin, asin¶
Sine, arcsine
sin x sin[x]
asin x asin[x]Where x is a numeric, returns
sin- the sine of
x, taken to be in radians. The result is between-1and1, or null if the argument is null or infinity. asin- the arcsine of
x; that is, the value whose sine isx. The result is in radians and lies between \(-\frac{\pi}{2}\) and \(\frac{\pi}{2}\). (The range is approximate due to rounding errors). Null is returned if the argument is not between -1 and 1.
