so I have x*y^2 + x*y = sin y and i try to solve for y'.

So far I have x2yy' + y^2 + xy' + y = cosyy'.

It looks as though as I am going to factor out the y' on the left side of the equation and then divide both side by y' but I am going to lose my y'??? I am a little stuck. any help or steps so a solution would be appreciated.
