http://www.geocities.com/asdfasdf23135/advcal18.JPG Well, I don't get the idea of the proof at all... I have no clue why they can let U be an open ball. Not all open sets are balls, and if they let U be an open ball, it doesn't not seem to me that the proof has covered ALL possibilities of...

1. If set A is compact, show that f(A) is compact. Is the converse true? Ans. f:M to N is continuous and A subset M is compact. Then f(A) is compact. The converse is not necessarilly true. For Ex: F(x)=0 for every x in R(real #'s) and k={0}. Then f^-1(k)=R is not compact. 2. If...

Hi, I just finished up a B.A. in Physics at UVa, but I had some major holes in my curriculum. I took Modern physics, QM, and then GR, but never took E&M and Stat. Mech.
