Synopsis
#include <flint/fexpr_builtin.h>AsinAcosAtanAcotAsecAcscAtan2Principal branches of the inverse trigonometric functions Asin(z) (\operatorname{asin}(z)), Acos(z) (\operatorname{acos}(z)), Atan(z) (\operatorname{atan}(z)), Acot(z) (\operatorname{acot}(z)), Asec(z) (\operatorname{asec}(z)), Acsc(z) (\operatorname{acsc}(z)), and the two-argument arctangent Atan2(y, x) (\operatorname{atan2}(y, x)).
