    See attached PDF for the compiled LaTex.
    I would prefer any solution include the Latex Source, however, if you are unable to use LaTex, you may use another format.

    Exercise 1

    Solve, using Fourier Transforms frac{partial^{2}u}{partial x^{2}}+frac{partial^{2}u}{partial y^{2}}=0
    for 0<y<H, -infty<x<infty subject to the initial/boundry
    conditionsbegin{gathered}u(x,0)=0
    frac{partial u}{partial y}(x,H)+hu(x,H)=f(x)end{gathered}

    Exercise 2

    Solve, using Fourier Transforms frac{partial^{2}u}{partial x^{2}}+frac{partial^{2}u}{partial y^{2}}=0
    for x<0, -infty<y<infty subject to u(0,y)=g(y).

    Exercise 3

    Solvefrac{partial u}{partial t}+v_{0}cdotnabla u=knabla^{2}u
    subject to the initial condition u(x,y,0)=f(x,y)Show how the
    influence function is altered bt the convection term v_{0}cdotnabla u
    .

    Exercise 4

    Solve, via Fourier Transforms:frac{partial u}{partial t}=k_{1}frac{partial^{2}u}{partial x^{2}}+k_{2}frac{partial^{2}u}{partial y^{2}}
    with the initial condition u(x,y,0)=f(x,y)

    Exercise 5

    Solve, via Fourier Transformsfrac{partial u}{partial t}=kleft(frac{partial^{2}u}{partial x^{2}}+frac{partial^{2}u}{partial y^{2}}right)
    with x>0 and y>0 and the initial condition u(x,y,0)=f(x,y) and
    the bound conditionsu(0,y,t)=0qquadfrac{partial u}{partial y}(x,0,t)=0
