1. Obtain an expression for operator of coordinate in momentum representation. To this end
begin with definition of the average coordinate
x = ∫ψ*(x)xψ(x)dx
express the wave functions as wave packets in terms of plane waves, and rewrite the
expression for average coordinate in such a way that it would have a form of an operator
acting on the wave functions in the momentum representation.
