Help with an approximation

  1. Feb 10, 2004 #1
    I'm doing a problem on Van-der Walls interaction and was told in the hint of the problem to use the approximation kT>>hw to simplify


    I have no idea how to apply this approximation to simpify the problem.

    Do you remember differential approximation? (Or taylor series?) If kT >> hw, then (hw / kT)^2 is going to be negligibly small...
