Perhaps the differentials are transposed. The following is exact:
$$(\sin x - x\sin y) \,\mathrm d y + (\cos y + y \cos x)\,\mathrm d x = 0 \\ \implies y\sin x + x\cos y = c$$

you mean the dy and dx should be interchanged , so that the equation is EXACT ?

i tried this , but still didint get the answer . Is there any other alternative for this question?
