Homework Statement
how does one solve the following equation to obtain E as a function of K.
Homework Equations
cos(k*a)=P*sin(u*a)/u*a + cos(u*a),
where u=sqrt(2*m*E)/h-bar
The Attempt at a Solution
theres no way this can be solved analytically,however how to go...
Fine but how do you go about the proof?
forget about in the wavemechanics
just a general proof in bra-ket notation,showing that degenerate states are orthonormal.
Homework Statement
Are all electronis states orthonormal?
I mean the degenerate states ie [n,l,m>states corresponding to same energy
for example can one write
[2,0,0>=a[2,1,-1>+b[2,1,0>+c[2,1,+1>
