1 Objectives
Consider the Poisson equation
on the interval [−L,L] subject to periodic boundary conditions.
• Determine the energy functional corresponding to Eqn. 1.

• Assuming L to be very large and ρ = e−x + c, determine the constant c such that Eqn. 1 is well posed.
• For L = 10, solve Eqn. 1 using the finite-element, finite-difference, and Fourier methods. Determine the corresponding energy, and demonstrate convergence of the methods with respect to discretization, while determining their convergence rates. Compare and contrast the results obtained, and discuss the relative efficiency of the approaches.
