Homework Help: Why we cannot solve quantum sho directly by fro envious series.

  1. Sep 18, 2014 #1
    I have just learnt the quantum harmonic oscillator
    When we start to Solve the schodinger equation. y"= (K - x^2) y
    We look at large x behaviour and use a substitution y = u(x)* exp(-x^2 /2)
    to approximate the large x behaviour first,
    then we use series method to solve the equation which is in terms of u(x)

    I wonder if we can use power series or froenvious series to solve the equation at the very beginning

    If you don't believe your teachers or the text book authors, there is no reason for you to believe us.
    You only have one option remaining: try it and see ;)
