sine inverse, results in degree
t=asind(x)
:x real vector/matrix. Elements must be in [-1 1] . : :t real vector/matrix with same dimensions as x :
The entries of t are sine inverse of the corresponding entries of x. Definition domain is [-1, 1]. The results are in [-90 90];
x=[-1 0 1 `sqrt`_(2)/2 -`sqrt`_(2)/2 `sqrt`_(3)/2 -`sqrt`_(3)/2];
