• Both the domain and the range of the hyperbolic arccosecant function include all real numbers except zero.
• The range of the arccosecant function is limited to values of y between, and including, -90 and 90 (-/2 rad and/2 rad), with the exception of 0
• If we are operating on some variable x, the arccosecant of x is denoted cscÀ1 (x) or arccsc (x) The inverse of the secant function is the arcsecant function.
• If we are operating on some variable x, the arctangent of x is denoted tanÀ1 (x) or arctan (x) The inverse of the cosecant function is the arccosecant function.
