7.Н. Show that every number in the Cantor set has a ternary (-base 3) expan- sion using only the digits 0, 2 7.I. Show that the collection of "right hand" end points in F is denumerable. Show that if all these end points are deleted from F, then what remains can be put onto one-one correspondence with all of [0, 1). Conclude that the set F is not

1. (5 points) The wave function for a particle in an infinite square well (0<xca) at t-o is given by: (x,0)-Finm). Which one of the following is the wave function at time t? (Clearly circle your choice.) 2 . 3x 2 . 3m (a) (x.1)-Vasin( )cos(Ey/A) 2 . 3tx sies-E/n) (c) Both (a) and (b) above are correct. (d) None of the above.
x?. Is f a one-to-one 3. (10 points) Define a function f on a set of real numbers by the rule f(x) correspondence (bijective)? If so find its inverse. Formally justify your answer.
4. (20 points). 5-function perturbation. Consider a particle in a one-dimensional infinite square well with boundaries at x--a and x-a. We introduce the following δ-function perturbation at V'(x) 00(z). a. Compute the first-order corrections to the energies of the particle induced by the perturbation b. Recall that you solved this problem exactly in problem set 4 (Griffiths 2.43). Compare your perturbation theory result to the exact solution

There are ____possible one to one correspondence between the sets if p must match with 4. b if in each correspondence p must match with 4 and y must match with 1. There are ___possible one to one correspondence between the sets if p...
