Hola El plano z = 1 corta a la esfera de radio?2 centrada en origen en la curva sobre el plano x y?(2 - x^2 - y^2) = 1 (2 - x^2 - y^2) = 1^2 x^2 + y^2 = 2 - 1 x^2 + y^2 = 1 círculo centrado en origen de radio 1 Es conveniente usar coordenadas cilíndricas con límites z1 =?(2 - x^2 - y^2) =?(2 - r^2) z2 = 1 divergencia de f?. F =? Fx/?
X +? Fy/? Y +?
Fz/? Z?. F =?(x)/?
X +?(-y)/? Y +?(2 z^2)/? Z?.
F = 1 + (-1) + 4 z?. F = 4 z.
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.
