think i ended up solving it sometime last year.. think the equation factors to something like: (x-4)*(x-2)*(x-2)=0 or something like that.. roots are then 4 & 2.. can't remember exactly but hope this points you in the right direction... oh x=r/a) of course..

in a 1 d system. x measured WRT an inertial frame k, are the following, valid Galilean transformations: x=x'- sin(wt) and x=x'3Not sure where to go with this... I can't find any relevant material anywhere.

i am working on the same problem, and i am stuck on one particular part, when i take the derivative and set it equal to zero i end up with a cubic polynomial, like (r/a)^3 - 6(r/a)^2 + 8r/a - 4 =0 not sure it this is correct, and if it is then do i need to use a graphing program...

Homework Statement For an electron in a hydrogen atom: in state psi(100): find (del-x)(del-p) where del x = integral of :[psi (x-<x>)2 psi]dv and del p = integral of: [psi(p-<p>)2 psi]dv Homework Equations The Attempt at a Solution i attempted to multiply out both...

oh right, my lecture notes said that (dx/dp) = 1... i then assumed that (dp/dx) = 1.. oh yes and p is velocity dependent, now i get it... thanks!

can anyone tell me why the poisson brackets for {x,p} = 1 ..from (dx/dx)(dp/dp) - (dx/dp)(dp/dx)... shouldn this equal 0??
