#### Answer

$$- \cos y + C$$

#### Work Step by Step

\eqalign{ & \int {\frac{{dy}}{{\csc y}}} \cr & {\text{basic trigonometric identity csc}}\theta = \frac{1}{{\sin \theta }} \cr & \int {\frac{{dy}}{{\csc y}}} = \int {\frac{{dy}}{{1/\sin y}}} \cr & = \int {\sin y} dy \cr & {\text{use integration formula from table 4}}{\text{.2}}{\text{.1}} \cr & = - \cos y + C \cr}
