Homework Help: Mathematica trouble here

  1. May 15, 2012 #1
    1. The problem statement, all variables and given/known data
    How do I implement the series k(tilde) = k0 + [itex]\sum_{i,j}[/itex] ki,j [itex]\epsilon[/itex]1i [itex]\epsilon[/itex]2j into Mathematica.
    This is a 2 parameter asymptotic expansion and I am plugging this into my equation I am trying to solve.
    Also I don't know how to implement the O[[itex]\epsilon[/itex]1} and O[[itex]\epsilon[/itex]2] terms in the file as well.
    Note I am using the LogicalExpand[...] then Solve[..] to get my constants k1, k2, ...

    2. Relevant equations
    k0 = -π/sqrt(3)


    3. The attempt at a solution
    I tried k-tilde = k0+Sum[k[i,j]*[itex]\epsilon[/itex]1^i*[itex]\epsilon[/itex]2^j,{i,1,5},{j,1,5}] in Mathematica but this isn't correct.
    Someone please help.
