Taylor Polynomial Approx help!

  1. Aug 15, 2011 #1
    1. The problem statement, all variables and given/known data
    f(x,y) = ln(3y-8x)

    Derive the first and second order Taylor polynomial approx, L(x,t) and Q(x,t), for T(x,T) about the point (1,1)


    2. Relevant equations
    -None-


    3. The attempt at a solution
    I do not understand what the question wants, nor do i want a solution. I would love to know how do i proceed to do the questions, probably a few steps and directions as i do want to learn how to tackle the question. Thank you!

    Look in your textbook, or Google "Taylor expansion". For example, see equation (30) in
