    1. The problem statement, all variables and given/known data

    Formally solve the following boundary value problem using Fourier Transforms.

    2. Relevant equations

    ([tex]\partial[/tex][tex]^{2}[/tex]u/[tex]\partial[/tex]x[tex]^{2}[/tex])+([tex]\partial[/tex][tex]^{2}[/tex]u/[tex]\partial[/tex]y[tex]^{2}[/tex]) = 0

    (-[tex]\infty[/tex]<x<[tex]\infty[/tex],0<y<1)

    u(x,0)= exp[tex]^{-2|x|}[/tex]

    (-[tex]\infty[/tex]<x<[tex]\infty[/tex])

    u(x,1)=0


    (-[tex]\infty[/tex]<x<[tex]\infty[/tex])

    u(x,y)[tex]\rightarrow[/tex] 0 uniformaly in y as |x| [tex]\rightarrow[/tex][tex]\infty[/tex]

    That's 3 posts and no work shown on any one of them. You *must* show an attempt at a solution, or we cannot be of help to you. Please click on the "Rules" link at the top of the page.
