given that H=1/2mpx^2 + 1/x mw^2x^2
given that m is the effective mass of the oscillator and v is the frequency and w is the angular frequency defined by w=2piv.
given that (A+) = 2m^(-1/2)(px+1mwx) and (A-) = 2m^(-1.2)(px-imwx)
(a) show that (A+)(A-) = H-1/2hv and (A-)(A+)=H+1/2hv
(b) show that [(A+),(A-)]=-hv anbd that [H,A+]=hvA+ and [H,A-]=-hvA-
