REVIEW/study:
Here's a brief
list of the main topics covered this quarter.
Review the examples done in your text and lecture, plus any problem
types that you found more difficult when you encountered them on your
homework, quizzes, or exams.
PRACTICE:
If you need them, here are some
Practice Integrals
(+
solutions, but first try them yourself!)
Here's the
final exam ARCHIVE (contains almost all final exams since
2005, + answers)
Here's
another final, from 2004, with detailed solutions.
The final exam is comprehensive and about 10 pages long.
Read each question very carefully and follow directions. Check your work
if you have time.
Start with whichever question looks easiest, work carefully, do your
best, and don't spend too long on any one problem or page.
Show your work and use correct notation! Answers with incomplete/missing
work may not get much credit.
There are different versions of the exam. Do not cheat
-- it is a serious academic offense and will not be tolerated.
-------------------------------------- Previous weeks: -----------------------
Week 10 (last):
This week we'll discuss some applications of diff eqs on Monday (topics from 3.8, 9.4), then review for the final for the rest of the week.
In Quiz Section:
Tuesday: Hwk Q&A + Bring Worksheet
"Review for the Final Exam- part I"
Thursday:
Hwk Q&A + Bring Worksheet
"Review for the Final Exam- partII"
Homework: Sections 9.1 & 9.3 close Tuesday, and 3.8 MiscDiff Eqs is due Thursday.
Week 9 (March 4-8):
In Lecture: Sections
8.3, 9.1, 9.3, and some of 3.8.
Please print and bring this handout: §8.3.
Section 8.3
covers a Physics application: Center of Mass. The topic starts with a
summation in the case of discrete data and eventually replaces the summation
with an integral for the case of a thin plate.
Many applied problems in
Physics, Engineering, Economics, etc can be modeled using Differential
Equations. They are often very difficult to solve and we will focus on the
just easiest cases. The notation and terminology are introduced in §9.1.
Then we discuss Separable Equations in §9.3. These are differential
equations that can be solved using the techniques we have been studying this
quarter. Several applications are covered, including mixing problems.
In Quiz Section:
Tuesday: Hwk Q&A & Midterm Return.
Here are the solutions to Midterm 2:
version 1 &
version 2

There will be an extra review Q&A session on Wednesday, 4-5:20,
PAA A110.
CLUE is holding a review session for Math 125 on
Wednesday night, 8:00-10:00pm, in MGH 38
Week 7 (Feb 18-22):
In Lecture: Integrals requiring several techniques
were presented in Section
7.5. Lots of practice is the only way to get good at
integration. Here are also some
Extra Practice Homework Problems in
addition to the usual WebAssign homework this week.
We have already seen how to approximate integrals using Riemann Sums.
This works quite well if we use midpoints for our sample points.
Section 7.7 introduces two more techniques for approximating
integrals, the Trapezoid Rule and Simpson's Rule. These are key
techniques for use in applications. You may skip the error estimation
formulas.
Improper Integrals are covered in Section 7.8. These
are a combination of a Definite Integral and a Limit. There are two
types of Improper Integral and you should understand the difference. You
should understand convergence and divergence. You'll probably have to
review one-sided limits when studying integrals that are improper
because of discontinuity. L'Hospital's Rule is also useful here. Here's
a
limits
quick-review sheet.
In Quiz Section:
Tuesday: Hwk Q&A (7.1, 7.2) &
Quiz #4 (from
7.2 & 7.3)
Thursday:
Worksheet 6, Integration Techniques (<-- please
print & bring with you!)
Homework: Sections 7.4&7.5 close on Wednesday. (Afterwards, work on 7.7&7.8, and review/practice for the midterm.)
This week's lecture notes:Solutions to section 7.5 Handout, Wednesday (7.5/7.7)
Last week's lecture notes: Monday (7.2/7.3), Wednesday (7.3/7.4), Friday (7.4/7.5)
Week 6 (Feb 11-15):
In Lecture:
This week we'll continue with methods of integration. You may find that
you need to review some trigonometry, and
completing the square,
when studying Section 7.3. Many students find this
section difficult. The final integration technique we cover is
Partial Fractions in Section 7.4. This is a fairly complex
algebraic technique for simplifying rational functions. To make things
easier, we cover only the cases where the denominator factors into
linear terms, is itself an irreducible quadratic, or factors into
(possibly repeated) linear terms times a single irreducible quadratic
term. This should give you the basic idea of the technique. You'll
probably have to
review long
division of polynomials. The technique of
Rationalizing Substitutions is also in this section.
Integrals requiring several techniques are presented in Section
7.5. These can get rather difficult. In this section we'll also
practice identifying which method is most likely to work.
In Quiz Section:
Tuesday: Hwk Q&A (7.1, 7.2) &
Quiz #3 (from
6.4 work)
Thursday:
Worksheet 5, Partial Fractions (<-- please
print & bring with you!)
Homework: Sections 7.1&7.2 close on Tuesday, and section 7.3 closes on Thursday night.
This week's lecture notes: Monday (7.2/7.3), Wednesday (7.3/7.4), Friday (7.4/7.5)
Week 5 (Feb 4-8):
In Lecture:
This week we'll wrap up the Ch 6 applications (a bit more about work,
then discuss average value in 6.5), and we'll start studying
additional methods of integration. Chapter 7 is devoted to techniques
for computing integrals. Some of these can be rather challenging. We
start with Integration by Parts in Section 7.1. This is basically the
Product Rule done backwards. Once you get the hang of it, you should not
find it too difficult. The Trigonometric Integrals in Section 7.2 are
needed to do Trigonometric Substitution in Section 7.3. Some of the
integrals in Section 7.2 can get quite lengthy (and tricky, see Example
8).
In Quiz Section:
Tuesday: Homework Q&A and midterm return.
Here are the solutions:
version 1 and
version 2.
Thursday:
Worksheet 4, Integration By Parts (<-- please
print & bring with you!)
Homework: 3 assignments from Sections 6.4/6.5 close on Thursday night. <<<--- This is a hard homework -- start it early!!
This week's lecture notes: Monday (6.4/6.5), Wednesday (7.1), Friday (7.2, with a couple extra examples)
Week 4 (Jan 28-Feb 1):
MIDTERM 1: Thursday,
Jan 31, in your quiz section
It covers: 4.9, 5.1-5.5, 6.1-6.3
Bring: a scientific (non-graphing, non-integrating) calculator, one
8.5x11 handwritten sheet of notes (one or two-sided).

Week 3:
In Lecture:
Stewart 6.1-6.3. This week we'll discuss some applications of integrals:
area between curves, and volumes of 3D solids of revolution. Many
students have trouble visualizing these 3D solids. You should understand
when to integrate with respect to x or y, and when to use shells or
washers.It is important to understand how the formulas are derived. This
helps you to learn how to apply integration to the problems you
encounter in other fields.
