Homework Help: Applying Cantor's diagonalization technique to sequences of functions

  1. Jan 14, 2012 #1
    As usually, I type the problem and my attempt at the solution in LaTeX.



    Ok, so for the last part (c), I obviously have the diagram down, now I just have to construct the nested sequence of functions that converges at every point in A. I drew a diagram to help illustrate the idea.


    Would I need to do induction on two variables? (m and k)

    Bump. This stuff is only undergraduate analysis, I know someone can help.
