Determine Whether the Improper Integral Converges or Diverges, and If $$\int _ { \pi / 2 } ^ { 5 \pi / 6 } \frac { \cos x } { \sqrt { 1 - \sin x } } d x$$

Short Answer

Determine whether the improper integral converges or diverges, and if it converges, find its value. $$\int _ { \pi / 2 } ^ { 5 \pi / 6 } \frac { \cos x } { \sqrt { 1 - \sin x } } d x$$
