    It is given that that a Fourier Cosine series of teh function f(x) is given by (see file)
    A PDE is given by:

    u_t = u_xx 0<x>Pi t>0

    With boundary conditions:

    u_x(0,t) = u_x(pi, t)=0

    1. Determine all the solutions of the PDE that satisfy these boundary conditions.
    2. find teh solution that satisfies in addition the initial condition u(x,0) = f(x)
