Consider a linear harmonic oscillator and let, yo and y, be its real, normalized ground and first excited state energy eigenfunctions respectively. Let Ayo + Byi with A and B real numbers be the
wave function of the oscillator at some instant of time. Show that the average value of x is in
different from zero. What values of A and B maximize (x) and what values minimize it?
