Does anyone know how this works ?
I have dψ = (x^2 -cy^2 )dy
And my physics teacher says it is (or can
be) a harmonic function (Δψ = 0)
Can anyone explain ?
Calculate the first order energy correction
for the one dimentional non-degenerate
an harmonic oscillator whose harmiltonian
id written as;
H^ =−(h^2 /(2m)) (d^2 /dx^2 ) +(1/2)kx^2 +(1/5)Υx^3 +(1/(12))βx^4
