Why is equation (1) not a polynomial equation and equation (2) not a polynomial in y?
(1) dy/dx + sin(dy/dx) = 0
(2) (dy/dx)2 +(dy/dx) - sin2y = 0

Being a equation and a polynomial equation is very different. Functions like sinx, lnx, ex are not considered polynomial quations. They are transcental functions.
