1.	\left. \begin{array} { l } { I = \int \sqrt { 1 + \operatorname { sin } x } d x , \text { then } } \\ { - 2 \sqrt { 1 - \operatorname { sin } x } + C } \\ { \operatorname { sin } ( x / 2 ) + \operatorname { cos } ( x / 2 ) + C } \\ { \operatorname { cos } ( x / 2 ) - \operatorname { cos } ( x / 2 ) + C } \\ { 2 \sqrt { 1 - \operatorname { sin } x } + C } \end{array} \right.
