## Assignments

Assignments are due at the

start of class
on the due date. (Plan ahead!) There will be a small but
annoying grade penalty for loose pages or particularly messy
work. Also
note that the difficulty of these problems will vary quite a bit --
some should be completely routine, and some will take lots of persistence!

- Assignment 1: from the textbook. Chapter 2: 1, 2, 4, 13, 23, 28, 37.

additional problem X1: How many paths are there from the origin to the point (4,7,8), if we
define a path to be a sequence of steps, and each step to be a move of
distance of 1 in any of the three positive coordinate directions?

Due 18 Sept. Solutions.
- Assignment 2: from the textbook. Chapter 3: 2 (don't start with this one), 5, 8, 11, 12, 16, 18, 19. Due 4 Oct.
