2. Solve the eigenvalue problem associated with the x operator in a rectangular coordinate system subject to a Neumann boundary condition at x = 0 and a Robin boundary condition at x = 1. Thus, do/dx (0) = 0 do/dx (1)+A(1) = 0 where A is a constant coefficient. In completing the solution: ii. Determine the values of any constants of integration (an and/or br) needed for (x) to represent an orthonormal basis set, and Describe how to solve for the characteristic values (i.e., eigenvalues, An).
