PHYS 4840 Mathematical and Computational Physics II
 
        Homework #5     Due 2013 April 09 --> NOW DUE APRIL 11 @ 11:00 am!

Textbook problems 5.2, 5.4, 5.6, 5.15, 5.17a

5.2: Please quantify your answers.

5.6: "...from a straight line to a quartic ..." implies that you should
     try fitting four different polynomials: first, second, third, and
     fourth-order.  Only fit Days 1 through 5.  Please report the 
     fitted/expected values for Day 6.

For 5.17a, please produce plots of Power vs Frequency for the sawtooth wave, 
for fs=0.2 and N=50; fs=0.2123 and N=512; fs=0.8 and N=4096.  Note that in
Matlab, 'a mod n' is scripted as "rem(a,n)", e.g., 2.1 mod 2 is 0.1, 4.1 mod
2 is 0.1, etc.
