12/8 Final exam is 1:30-4:30 pm Thursday Dec 16. Section 21 will take the
exam in Vincent Hall 113. Section 23 will take the exam in Murphy Hall
130.
Remeber to bring a number 2 pencil and your University ID. "All students must have their official University I.D. Card with them
at the time of the final exam and must show it to one of the proctors when
handing in their exam. The proctor will NOT accept a final exam from a
student without an I.D. Card."
11/26 There are some errors in the text for this week's homework set,
depending on which printing you have. I have first printing, and in it
there are incorrect
answers in the book for problems 6.2.43 and 6.3.23.
For 6.2.28, the
vector v in part a) should be [1, -2, 1]. For 6.2.43, they label the tank
as having an initial concentration of .5 lb/gal and it should be .25
lb/gal.
In general, the best way to check a solution is to
plug
it back into the differential equation and to ensure
it satisfies any initial conditions.
In the resources section, there is a link to the book's official
errata.
11/19 For homework 9, I have postponed problems from section 6.1 so that they will be due with assignment 10. I have posted quiz 3.
I updated assignment 9.
10/22 I will hold extra office hours on Monday October 25, 1:25-2:15.
9/24 I will hold extra office hours on Monday September 27, 1:25-2:15. I added a couple links about partial derivatives.

In 1.1, we discuss Malthus's model for population growth. Here is a copy of Malthus's An Essay on the Principle of Population. I got this copy from Project Gutenberg which is an excellent resource for public domain texts.
I have written a short tutorial on using a spreadsheet for Euler's Method. For the tutorial, I used Microsoft Excel, but hopefully other spreadsheets are similar. If you don't have a spreadsheet program and have a fast internet connection you could try OpenOffice.org. It's free software.
Here are two sites discussing partial derivatives: a very brief Math Tutorial and a longer page Brief Calculus.
