PH253: HW 5 is out

Homework 5 is now out. Since I'm a little late in getting it out, you can turn it in Friday instead of Thursday.

Recall that you can turn in problem 4b from Exam 1 for an additional 1.5 points (5%) on Exam 1. You can turn this in with HW5 (at the latest).

  2. on problem 7a, is the question asking us to put the equation in terms of E and then in terms of a

    OR

    try to isolate E and a on the same side in the same equation?

  3. When you plug in the given formula for the wave function, isolate all the terms with like factors of x (be careful when you take the second derivative). There should be two x-squared terms.

    If there is to be a general solution, the x-squared terms have to be equal, which will give you an expression for a.

    I'll post some hints shortly.
