This is the homepage for math 332. Check back from time to time for info on the class.

Here's the syllabus for the class. We should be in room 414, and my office is room 352. (The syllabus is wrong.)

Since the trickiest integrals are the partial fractions, I've worked out 3. Please e-mail me if there are any mistakes!

Here's the first review homework due this Wednesday.

You can also start to look at the next three review homework sets: On logarithms, derivatives and integrals. The logarithms and derivatives are due on Friday while the integrals will be due Wednesday the 23rd.

The homework from section 1.1 is: 4, 5, 6, 8, 11, 12 (By the way, it's true that the dates can be tricky to determine, but this claim has been grossly exaggerated. There's accurate data on how much C14 there was going back thousands of years), 13, 17, 18, 20. Because of Wednesday's class being canceled, the 1.1 homework will now be due on Monday January 28th. I'll post solutions on Monday, that way you can see how to do the problems, in case there are any questions.

The first set from section 1.2. Start with checking to make sure that the answers we came up with in class actually solve the differential equation then do:

1, 3, 6, 9, 10(recall your trig functions), 15 (partial fractions might be helpful here), 18, this will be due on Monday. We'll start initial value problems and mixing problems on Monday.

From 1.2: In addition to solving the problems, find all missing solutions: 24, 25, 26, 28, 30, 31, 32

For Friday February Fifteenth on mortgage and interest rates.

Mixing problems, which I had meant to post on Friday, so, let's have them due on Friday Feb. 22nd instead. Also, for Friday, from section 1.3 please do problems 2, 4, 6, 7-10 (you can print up the solutions and then draw your solutions, don't bother turning in the computer generated solutions, just comment as to whether or not it matched what you thought).

Taylor series problems. You can also check out your calculus book or Wiki or Wolfram for more information on the Taylor series.

The spreadsheet for your homework is here.

Here's the second homework problem set on the Euler method, I also included some of the linear approximation to try to get people a little more practice on that.

Solve the following 2 differential equations in closed form.

    & y(0) = 5

     & y(0)=0

Solve both the above two equations and the equation below

 & y(0)=0.5

Try different step sizes, and note that if you want to solve the equation over the same range for smaller step sizes, you need to include more points. E-mail me the solution, try to include graphs as well.

Homework on partial derivatives and the existence theorem due on Monday.

Homework set 1.5: 2, 4, 6, 8, 9, do 10 but for dy/dt=(1+|y|)-1, 18

and Homework 1.6 2, 4, 6, 7, 8, 11, 14, 16, 17, 19, 20, 22-27, 29, 30, 32, 33-37, 39, 40

Due Friday March 14th.

And here are solutions. This is password protected, we'll talk about it in class.

Here is a practice test for the upcoming test on Wednesday January 30th. Here are the solutions.

Here is a practice test for the upcoming test on Wednesday March 5th. Here's some example mixing problems.

After test 2

Homework for section 1.8: 10, 12, 13, 20 22(for 22, just right down what form you think the particular will take). This is due Friday March 28th.

Homework for section 1.9: 2, 4, 5, 10, 12, 16, 18, 21 - note that for some you just have to set up an integral. This is due Monday March 31st.

Here's a practice test for sections 1.5-1.9 and solutions.

After test 3

Homework for section 2.1, this is difficult and time consuming, so I strongly recommend starting it now, and then poking at it some more over the weekend.

Section 2.2 2, 4, 6, 8, 10, 11, 14, 21, 23-26 due on Monday.

Section 2.3 will be the last homework, and included on the test on Friday April 25th!

Section 2.3 2, 4, 7, 8, 10, 12, 16, 18, 19

Here's the practice test and the graphic and the solutions for test 4.

Here's a practice final and its solutions.
