The Identity X2+y22x2 Y22+2xy2

Answer (x2 y2) = (x y)2 – 2xy or (x – y)2 2xy Consider the equation (x y) 2 = x 2 y 2 2xy (1) (x – y)2 = x 2 y 2 – 2xy (2) From equation (1) x2 y2 = (x y)2 – 2xy x2 y2 = (x – y)2 2xy.

The identity x2+y22x2 y22+2xy2. (y2 2xy)dx− x2dy = 0 we have M(x,y) = y2 2xy and N(x,y) = −x2, which leads to ∂M ∂y = 2x2y and ∂N ∂x = −2x Since ∂M ∂y 6= ∂N ∂x the equation is not exact However, 1 M ∂N ∂x − ∂M ∂y = − 2 y which implies that thereexists an integratingfactor, dependingonly on y, which satisfies 1 µ dµ dy = − 2 y An.
