Wow...okay, I guess I'll end up with an expression in terms of Ci's. Also, when you said "these remaining lines are all wrong" did you also mean that I was wrong to make the following assumption: since normalized, => <ϕi|ϕi> = 1

Vela, Thank you for your response. However, can I use the fact that I know: Σ|ci|^2 = 1 (i.e., the state is normalized) to obtain an expression without Ci? For example, when calculating mean energy <H>: Expectation energy <H> is defined as: <H> = <Ψ|H|Ψ> *Note, (my mistake) my...
