dy/dx + sin y/x=y/x y/x=v dy/dx=v+xdv/dx v+xdv/dx+sin v =v xdv/dx=---sinv dv/sinv =-dx/x integrate and solve ans. will be xsin(y/x)=c(1+cos y/x) if i am right dont forget to rate

xdy/dx - y+siny/x=0  xdy/dx=y-xsiny/x dy/dx=y/x-siny/x xdv/dx+v=v-sinv xdv/dx=-sinv logIcosecv-cotvI= -logx+logc ( cosecy/x-coty/x)x=c |
