datatable.math.arcsin()¶
Inverse trigonometric sine of x
.
In mathematics, this may be written as \(\arcsin x\) or \(\sin^{-1}x\).
The returned value is in the interval \([-\frac14 \tau, \frac14\tau]\),
and NA for the values of x
that lie outside the interval [-1, 1]
.
This function is the inverse of sin()
in the sense
that sin(arcsin(x)) == x
for all x
in the interval [-1, 1]
