Ph314, Spring 2009, Homework Assignment #7

---

K. Krane, "Modern Physics". Chapter 7, Problems 4, 5 and 11 (1 pt. each); Problem 6 (2 pts.); and either Problem 13, or Problem 15 (each worth 2 pts.).

Problem 13 is a good exercise for integrating by parts -- one has to use the integration by parts scheme four times!, but it is a pretty straightforward job. In problem 15, by contrast, you don't need to integrate because between a₀ and 1.01a₀ the function does not change very much, so that one can approximate the integral by the function value at a₀ multiplied by the range width, i.e., by 0.01a₀.
