¿Es normal querer saber de alguien con mucha frecuencia?

REVISA PUES Tienes un revoltillo , pues no está en R^2 NI TAMPOCO en R^3 Actualiza. Edito nuevamente Creo que tienes un sistema con x+4y-8=0 ; z - 1=0 Haciendo y= t, se tiene , x+4t= 8? X=8 -4t ASI Las ecuaciones paramétricas serán x= 8?4t y= t , ...t?

IR z=1 Pero no tiene contínuas. Revisa los videos https://www.youtube.com/watch?v=I1x9fIUs... https://www.youtube.com/watch?v=OY6xwyg4... https://www.youtube.com/watch?v=UGtqIb-n...

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.
