Principal branches of the inverse trigonometric functions Asin(z) (asin⁡(z)\operatorname{asin}(z)), Acos(z) (acos⁡(z)\operatorname{acos}(z)), Atan(z) (atan⁡(z)\operatorname{atan}(z)), Acot(z) (acot⁡(z)\operatorname{acot}(z)), Asec(z) (asec⁡(z)\operatorname{asec}(z)), Acsc(z) (acsc⁡(z)\operatorname{acsc}(z)), and the two-argument arctangent Atan2(y, x) (atan2⁡(y,x)\operatorname{atan2}(y, x)).
