var Arcsin = Pm.Atan(x / Pm.Sqrt(-x * x + 1));
var Arccos = Pm.Atan(-x / Pm.Sqrt(-x * x + 1)) + 2 * Pm.Atan(1);
var Arcsec = Pm.Atan(x / Pm.Sqrt(x * x - 1)) + Pm.Sign(x - 1) * 2 * Pm.Atan(1);
var Arccosec = Pm.Atan(x / Pm.Sqrt(x * x - 1)) + (Pm.Sign(x) - 1) * 2 * Pm.Atan(1);
var Arccotan = Pm.Atan(x) + 2 * Pm.Atan(1);
