Dear Experts,

I am having difficulty undersanding the pattern when working with operators which is part of the work to evaluate <x^2>. See attached jpg.

Likewise the same with evaluating

Thanks

On that basis,

I calculate

The first 2 calculations are wrong by my lectures notes, so obviously dont understand the definition.

For example, it there is an adding operator, I will sum it with n. Ie, adding a_+ operator to n+1 gives n+2, subtracting a_- to n gives n-1 etc..... - Nov 14th 2010, 10:58 AMmr fantastic
