Homework Assignment # 2
(Due Thursday, February 9 at 8:40 am in Computer Lab.)
Agenda and readings for the week of February 5:
Readings marked NR are from Numerical Recipes: The Art of
Scientific Computing, 2 
edition (in C). Readings
marked LN are from the course lecture notes to be found at

, and for periodic functions; IEEE arithmetic; care with
change of variables at limiting cases.
Note: For the programs in this problem set we face a small
notational difficulty. We have been using the variable n(r) to
represent the number of electrons per unit volume throughout space.
It would make sense then to define an array n[] to hold the values
of the electron density. However, n is so commonly used as an
indexing variable (particularly in Numerical Recipes) that this
is likely to cause difficulties. Thus, we shall use the array rho[]
to represent the electron density n(r).
