Homework Help: Associated Laguerre polynomials .

  1. Dec 3, 2014 #1
    1. The problem statement, all variables and given/known data
    Show that L11(x) and L12(x) are precisely the polynomials for 1s and 2s orbitals. What is the role of variable x in each case?

    2. Relevant equations
    L1n(x) = d/dx Ln(x), n = 1, 2, 3...

    3. The attempt at a solution
    Because L1(x) = 1 - x
    L2(x) = 2 - 4x + x2:
    I did:
    L11(x) = d/dx L1(x) = d/dx (1 - x) = -1
    L12(x) = d/dx L2(x) = d/dx (2-4x+x2) = 2x - 4 = 2(x - 2)....I wonder if x is a different function of radius in 1s and 2s orbital polynomials? I am also confused as how to find polynomials for 1s and 2s orbitals? Could anyone hint pls?
    For sure, I undersand that
    L11(x)= 1 because of 0 nodes...hence 1s
    L12(x) = 2x -4 because of 1 node.....hence 2s
