Function

*f*of {*x*∈ \(\mathbb{R}\) |*x*≠*k*π where*k*∈\(\mathbb{Z}\)} in \(\mathbb{R}\) defined by*f*(*x*) = \(\dfrac{1}{\sin{(x)}}\).### Notation

- The cosecant function is noted as “cosec(
*x*)” which is read as “cosecant of*x*.” - Sometimes, the notation “csc(
*x*)” is used to indicate “cosecant of*x*.”
