Answer
          __        __
    =  2\/ x  sin \/ x   + C
Explanation
    /       __
    | Cos \/ x  dx 
    /              
             __
       sin \/ x 
    = ----------- + C
         d    __
       ---- \/ x
        dx

             __
       sin \/ x 
    = -----------  + C
        1    -1/2
       --- (x)
        2

             __
       sin \/ x 
    = -----------  + C

           __ 
        2\/ x

          __        __
    =  2\/ x  sin \/ x  + C
    Above question was wrong sorry for that. 
    /       __
    | Cos \/ x  dx 
    /                           __
                          Let \/ x = t
                          Diff. w.r.t. x
                                       
                           1   - 1/2
                          --- x      dx = dt
                           2
                                  __     
                          dx / 2\/ x  = dt 
                                      
                          dx / 2t  = dt 

                          dx = 2t dt   

     /       
    =| Cos t . 2t dt 
     /      

       /       
    = 2| t . Cos t dt 
       /      

                  /       
    = 2t(sin t) - | 1. sin t dt 
                  /
    = 2t . sin t - (- cos t)

    = 2t . sin t + cos t
         __         __         __
    = 2\/ x . sin \/ x + cos \/ x
