dy/dx=x(2logx+1)/siny+ycosy

{tex}{dy\over dx}={x(2log\ x+1)\over sin\ y+y.cos\ y}{/tex}

{tex} (sin \ y+y.cos\ y)dy = [x(2log\ x+1)]dx{/tex}

Integrating both sides, we get

{tex} \int sin\ y\ dy +\int y.cos\ y\ dy = \int 2x.log\ x \ dx+ \int xdx{/tex}

{tex}-cox \ y + y\ sin\ y + cos \ y = x^2log\ x -{x^2\over 2}+ {x^2\over 2}+C{/tex}

{tex}=> y sin\ y =x^2.log \ x+ C{/tex}
