Homework Help: Solving the heat equation on the real line using fourier transforms

  1. Nov 23, 2011 #1
    1. The problem statement, all variables and given/known data

    Solve the heat equation

    on the real line ℝ with the initial conditions:
    u(x,0)= 1 if |x| [itex]\leq[/itex]1, 0 for any other value of x

    2. Relevant equations

    I don't even know where to start for this question, but I believe that I will have to use a fourier transform, and perhaps separation of variables, to find a solution to this problem

    3. The attempt at a solution

    I don't even know where to start.
