- Start by working through the corresponding exercises on the
**Final Exam Review sheet**(handed out in class, also available here). Many of these were assigned as homework exercises, so you should have already worked through them. - Also review the corresponding questions on
**the midterm exams**. I have uploaded solutions to the exams in the Files section of the course profile. - Of course you can also study the
**examples and homework exercises**from the corresponding sections in the textbook.

Here is a list of topics, according to the questions in the Final Exam Review sheet:

- Final Exam Review #1: Integrating by substitution (see also Exam #1 & Sec 5.6)
- Final Exam Review #2: Integration by parts (see also Exam #1 & Sec 7.1)
- Final Exam Review #3: Using integrals to find the area between two curves (see also Exam #2 & Sec 6.1)
- Final Exam Review #4: Using integrals to find the volumes of solids of revolution (see also Exam #2 & Sec 6.3)
- Final Exam Review #5: Integrals using trigonometric Substitutions (see also Exam #2 & Sec 7.3)
- Final Exam Review #6: Integrals using the Method of Partial Fractions (see also Exam #2 & Sec 7.5)
- Final Exam Review #7: Improper Integrals (see also Exam #2 & Sec 7.6)
- Final Exam Review #8 & #9: Infinite Series (Exam #3, Sections 10/2-10.5)
- Final Exam Review #10: Power Series (Sec 10.6 – Examples 1 & 2)

UPDATE: I have extended the document to include the Alternating Series Test (Section 10.4) and the Ratio Test (Section 10.5). You can download the new version of the document here:

The trickiest of these is probably the limit comparison tests. It may be helpful to look at some video examples:

]]>- From the Final Exam Review sheet (handed out in class, also available here):
- #5 (Sec 7.3: Trigonometric Substitutions)
- #6 (Sec 7.5, Method of Partial Fractions)
- #7 (Sec 7.6, Improper Integrals)

- Sec 6.1, Integrals for the area between two curves: (pp361-362): #1, 3, 4, 27
- Sec 6.3, Volumes of Revolution (p381): #1, 3, 5, 6

**Trigonometric Substitutions:**

Do #5(a), (b), (c), and (d) on the Final Exam Review Sheet. Take a look at the outline of how to approach these problems I posted in the discussion forum.

Actually we did #5(a) in class today. If you want to review it again (or missed class today), here is a video I did of a very similar example:

If you want to review this topic further, look at Examples 1, 2 & 4 in Section 7.3. You could also review #53 from Sec 7.5, which was assigned as a HW exercise.

**Method of Partial Fractions**

There are three types of partial fractions integrands we discussed, depending on the factors that appear in the denominator:

- “Distinct linear factors”: This is the most basic type, where the partial fraction decomposition has a constant coefficient for each distinct linear factor. For example, in Example 2 in Section 7.5, the partial fraction decomposition of the integrand is of the form:You should be familiar with how to solve for A, B and C in an example like this. If you need to review, look at Examples 1 and 2 in Section 7.5.#6(b) and #6(c) on the Final Exam Review Sheet are integrands of this type (after you factor the given denominators!)
- “Repeated linear factors”: Here the partial fraction decomposition must include terms with constant coefficients for each power of the repeated linear factor.For example, consider #17 from Section 7.5, where the integrand is.Since the (x+1) factor is repeated twice, the partial fraction decomposition must be of the form:I worked out the rest of this exercises here:
If you need to review further, look at Examples 4 and 5(c) in Section 7.5.

- “Irreducible quadratic facors”: If the denominator contains an irreducible quadratic factor, i.e., a quadratic term (such as x^2 + 9) that can’t be factored into linear factors. In that case we include a term in the partial fraction decomposition for such a quadratic factor, but the numerator isn’t just a constant but must be a linear term.This is the case with #6(a) on the Final Exam Review. Review in the example we did in class today, and also read Example 5(a) in Sec 7.5 carefully. You can also view this video by patrickJMT (who has a bunch of integration examples that you may find helpful!)

**Improper Integrals**

Do the three improper integrals in #7 of the Final Exam Review sheet. For each, first rewrite the integrals as a limit, and then evaluate the definite integral inside the limit–for each of these three, you can find the antiderivative by making a simple u-substitution. Finally evaluate the limit

Check back here later, I’ll post an example in case you need some guidance with these.

The Visual Calculus site I linked to previously also has a bunch of substitution method examples.

]]>You can play around with the “Visual Calculus” visualization of Riemann sums I showed in class on Monday. There are a number of such visualizations on the web; for example, take a look at Wolfram MathWorld’s Riemann sum page.

Khan Academy has a sequence of 10 short videos on Riemann sums which you may find helpful. Here is the first one:

]]>Here is the link to their Integral Calculus sequence of videos. Try taking a look at the first one, which starts with the same topic we started with yesterday:

**Antiderivatives and indefinite integrals**

Khan Academy’s videos are also on YouTube, which may be useful in case you want to watch on your phone or on a tablet:

Let me know if you find these videos useful (you can always leave a comment below). And of course let me know if you have any questions about the math!
