f(x) = sin-1( x ) [-1 , 1] [-pi/2 , pi/2]
f(x) = cos-1( x ) [-1 , 1] [0 , pi]
f(x) = tan-1( x ) (-inf , + inf) (-pi/2 , + pi/2)
f(x) = sec-1( x ) (-inf , -1] U [1 , + inf) [0 , pi/2) U [pi , 3 pi/2)
f(x) = csc-1( x ) (-inf , -1] U [1 , + inf) (-pi , -pi/2] U (0 , pi/2]
f(x) = cot-1( x ) (-inf , + inf) (0 , pi)
