Ok, I'm working with the Pauli Matrices, and I've already gone through showing a few bits of information. I've got a good idea how to keep going, but I'm not exactly sure about this one--
say M= 1/2(alphaI + a*sigma)
where alpha E C, a=(ax, ay, az) a complex vector, a*sigma=ax sigmax+ay...
Yes, r^2= az. Typo that happened when bolding. Sorry :(
But thank you very much for your response. THat's exactly what I need, more of a step by step thought process on how to solve a problem like this. It all seems a bit clearer now :)
Lagrangian Method-- 1st form? Zwangskraefte?
Mechanics will be the death of me. For some reason, I can do E&M, and particle stuff, but give me a pendulum, and I'm dumbfounded.
THat said, I'm working on some problems using Lagrangians, and the only book I have available to me is Goldstein...
I'm trying to analyze the reflection of a plane wave of energy E on the box potential where
v(x)= 0 for x<-a
-Vnaught for -a<x<0
infinity for 0<x
and I'm trying to solve the schroedinger eqn. through:
Phi(x) = e^ikx + r(k)*e^-ikx in...
Hello there. I'm currently dead beat on this problem, maybe because I'm not sure I quite understand what it's asking (I'm taking my upper level mechanics course in germany, and I don't have any books, and it's the second week, and I'm up at 4am with 2 problem sets due tomorrow, each half done...
