Linearize poisson-boltzmann equation

  1. Mar 30, 2010 #1
    1. The problem statement, all variables and given/known data
    Need to linearize the poisson-boltzmann equation to be used later in the problem. I simply have never linearized an equation and searching google didn't really help me understand.

    2. Relevant equations

    Just need an idea of how to go about this in order to complete the question.

    To "linearize" means take an expansion to its linear term. I am still stuck on this. Any help would be great.
