X+y2 x y24xy. Answer The equation is M(x,y)dx N(x,y)dy =0 with M = 4xy y^2 , M_y = 4x 2y N = 2y 2x^2 , N_x = 4x # M_y The equation is not exact , but (N_x M_y)/M = 2/y , depends only on y The integrating factor is 1/y^2 and leads to the equation P(x,y)dx Q(x,y)dy =0 , with P = 4x/y 1.

This is immediately obvious from the quadratic Taylor polynomial at $P_3$ as well, because$$T_{2,P_3}(x,y)=2x^22y^24xy=2(xy)^2$$The nature of this critical point is thus left in the dark by a study of the Hessian alone Let's do some testing suggested by the form of the quadratic Taylor polynomial. Δ > 0 There is minimum if f xx < 0 and a maximum if f yy > 0 Δ < 0 there is a saddle point Δ = 0 Further analysis is necessary So we have f (x,y) = 2x3 xy2 5x2 y2 Let us find the first partial derivatives. $\begingroup$ Does this proof work?.
