1. Consider the one-dimensional box, or infinite square well, of width a, with sides at x = 0 and x = a. The unperturbed problem is well-known: the eigenvalues are $E_n^{(0)} =$ $n^2?^2?/2ma = n^2E_1^{(0)}$, and the eigenfunctions are $u_n(x) = \sqrt{2/a}sin(n?x/a)$ (a) We now add a perturbation $H_1 = W cos(?x/a).$ Sketch the perturbed potential well as a function of x. Show that all the first-order energy shifts are zero. Is there a simple explanation for this? (b) Find the first order correction to the ground state wave function. Sketch the ground state wave function and the correction, showing that the particle is more localised around the minimum of the potential. (c) Discuss the constraints on W for perturbation theory to be a suitable approxima- tion method.

The following graph illustrates the weekly demand curve for motorized scooters in Moline. Use the green rectangle (triangle symbols) to compute total revenue at various prices along the demand curve. Note: You will not be graded on any changes made to this graph. On the following graph, use the green point (triangle symbol) to plot the weekly total revenue when the market price is $50,$75,$100,$125,$150, $175, and $200 per scooter. According to the midpoint method, the price elasticity of demand between points A and B is approximately Suppose the price of scooters is currently $125 per scooter, shown as point A on the initial graph. Because the demand between points A and B is . , a $25-per-scooter decrease in price will lead to in total revenue per week.

3. Given a directed graph G <V,E >, we define its transpose GT <V,ET > to be the graph such that ET = {<v,u >:< u,v >? E}. In other words, GT has the same number of edges as in G, but the directions of the edges are reversed. Draw the transpose of the following graph: C b a i d e f g h Perform DFS on the original graph G, and write down the start and finish times for each vertex in the graph. Assume that the nodes are in alphabetical order and the adjacency list for each node is also in alphabetical order (the algorithm does not rely on the ordering, this is only for the convenience of checking your answer). Now, perform DFS on the transpose GT, but in the upper-case DFS routine, consider the ver- tices in decreasing order of the finish times computed earlier. For convenience, we again assume that the adjacency list for each node is also in alphabetical order. Draw all depth-first trees con- structed in this DFS of GT. Consider all vertices from a depth-first tree, what can you say about the reachability of these vertices from each other in G? If you pick a vertex from a depth-first tree and another vertex from a different depth-first tree, are they reachable from each other in G?
