4.6.3 Graph of the inverse cosecant function

. . Graph of the inverse cosecant function The inverse cosecant function, y cosec is a function whose domain is  \ ( - , ) and the range is − \ { }. That is, cosec − −∞− ∪ ∞→−  ∪ :( ] [ , Fig. . and Fig. . show the graphs of cosecant function in the principal domain and the inverse cosecant function in the corresponding domain respectively.
