Arccsc (-2) =
Means 1 over the angle whose co secant is -2, which means the angle whose sin is -1/2, which is -30 degrees.
Arccsc (1.607) is the angle whose sin is 1/1.607 = 0.622 which is 38.48 degrees
Arccot (-0.555) is the angle whose tan is -1/0.555 or -1.801
which is -60.96 degrees

csc = 1/sin x=arcscs(-2)=arcsin(-0.5)= 210 or 330 deg
x = arccsc(1.607) = arcsin(0.622)=38.48 or 141.52
x=arccot(-0.555)=arctan(1.80)=60.97 or 240.97
