hello iitaspirant10 ...
see.. here is my solution....
cosy = xcos(a+y)
diff. both sides w.r.t. x,
-siny. y' = -xsin(a+y).y' + cos(a+y)
therefore.. y' = cos(a+y)/(xsin(a+y)-siny)
then take the value of x from the given ques. put it in the above... take lcm and you will get your answer...
and ya rate me... i u think ...... that the sol. is understood to u..
