Ecuaciones diferenciales, necesito aclarar algunas dudas, doy puntos?

Hola Hablas de funciones homogéneas que cumplan f(ux , uy) = u^n f(x,y) donde n es el grado de homogeneidad f(x,y) = x^2 + y^2 + 1 f(ux,uy) = u^2 x^2 + u^2 y^2 + 1 NO se puede sacar factor común u^2 así que f NO es homogénea (culpa del 1) b) f(x,y) = (x/(2 y)) + 1 f(ux,uy) = (ux/(2 (uy)) + 1 f(ux,uy) = (x/(2 y)) + 1 f(ux,uy) = f(x,y) f ES homogénea de grado 0 c).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
