MA 222, Spring 2013 sections 001 and 011
This is the webpage for my sections (001 and 011) of MA 222 for the spring 2013 semester. Mainly I will host the in-class quizzes, their solutions, and any other helpful documents.
For the course ground rules, you should visit the main MA 222 course webpage here
Overview
Lecture is held three times each week. Usually, we will spend a few minutes covering the previous quiz (if any), 5-10 minutes on a new quiz, 10 minutes covering homework problems, and the rest of the class will be new material.
Homework
The homework for this semester is administered through Cengage. It is your responsibility to be able to access the online homework and pay any necessary fees. Your online homework includes most of these problems. However, on the assignment sheet (available here), there are a few problems in bold face that are not included online. They will not be collected (unless otherwise announced), and you are still responsible for doing them on your own. They make for good quiz and exam questions!
I am more than happy to help you with your homework over e-mail. In your e-mails, you should indicate what you have tried so far - please don't just e-mail me asking "How do I do number 3?" but show me that you've at least attempted the problem. I will not give full solutions over e-mail but will offer hints and point out where you may have made mistakes. You should also be sure to e-mail me well in advance of the deadline. I cannot always respond to e-mails that are sent close to the deadline.
Quizzes/Solutions
Roughly once per week there will be a quiz about ten minutes in length and consisting of 1-2 questions that are based on the homeworks that have been due since the last quiz. There will be no make-up quizzes - if you miss a quiz, you will receive a zero for it unless you have a valid excuse (e.g. illness with doctor's note, verified family emergency, or other university-approved absences).
All quizzes are out of 10 points maximum unless otherwise noted. Your quiz scores are available on Blackboard.
None yet.
Expositions
Here are a few expository documents that may help explain some of the harder material for the course.
Exam 1
The first exam is on Wednesday, January 30 at 8:00 p.m in EE 129.
If you are ill and can not come to the exam, you should e-mail me immediately. Do not wait. In the event of this occurring, be prepared to present documentation from PUSH or another healthcare provider. Without this information you will not be permitted to take a make-up exam.
Review Problems for Exam 1
In addition to reviewing old homeworks (which should be your first priority), here are some extra problems you may want to consider while studying for the first exam.
- p. 251, #1, 5, 9, 15, 17, 21, 34, 35, 37, 40
- p. 291, #1, 7, 11, 23, 24 (hint for #24: \(\sin^2(2x)=1-\cos^2(2x)\))
Answers to the odd numbered problems are available in the back of your textbook. Full solutions to the even numbered review problems are available here.
Old Exam 1
Here are two sample exams that I gave my class in the fall 2012 semester. They are very similar, but there are subtle differences between the two. Please remember that
these exams will not be the same format as your exam 1 and it will not be authored by me. Your exam 1 will be written by the course coordinator and will consist
of somewhere in the neighborhood of 10-12 multiple choice questions.
Exam 2
The second exam is on Monday, February 25 at 8:00 p.m in PHYS 114.
If you are ill and can not come to the exam, you should e-mail me immediately. Do not wait. In the event of this occurring, be prepared to present documentation from PUSH or another healthcare provider. Without this information you will not be permitted to take a make-up exam.
Review Problems for Exam 2
In addition to reviewing old homeworks (which should be your first priority), here are some extra problems you may want to consider while studying for the second exam.
- p. 291, #7, 8, 12, 13, 14, 43, 45, 49, 51
- Hint for #43: \(\sec^2(3x)=1+\tan^2(3x)\)
- For #51, find the partial fraction decomposition but do not integrate the result.
- p. 397, #1, 2, 13, 15, 17, 21
Answers to the odd numbered problems are available in the back of your textbook. Full solutions to the even numbered review problems are available here.
Practice Exam 2
Here is a practice exam for exam 2. The answers are available here. This exam has never been administered at Purdue, so I don't have a good gauge for its level of difficulty. Your actual exam may be easier or harder.
Exam 3
The third exam is on Monday, April 1 at 8:00 p.m in EE 129.
If you are ill and can not come to the exam, you should e-mail me immediately. Do not wait. In the event of this occurring, be prepared to present documentation from PUSH or another healthcare provider. Without this information you will not be permitted to take a make-up exam.
Review Problems for Exam 3
In addition to reviewing old homeworks (which should be your first priority), here are some extra problems you may want to consider while studying for the third exam.
- p. 398, #19, 22, 23, 24, 26
- p. 424, #1, 2, 9, 10, 13, 16, 17, 20, 21
- p. 431, #13, 19, 30
- p. 434, #5, 45, 47
Answers to the odd numbered problems are available in the back of your textbook. Full solutions to the even numbered review problems are available here.
Old Exam 3
Here are two sample exams that I gave my class in the fall 2012 semester. They are very similar, but there are subtle differences between the two. Please remember that
these exams will not be the same format as your exam 3 and it will not be authored by me. Your exam 3 will be written by the course coordinator and will consist
of somewhere in the neighborhood of 10-12 multiple choice questions.
Note: Last semester we covered non-homogeneous second order linear equations before exam 3. As such, you cannot do number 8 given what we've covered in class so far. Instead, you can do the problem assuming that the right-hand side of the equation is zero. This corresponds to finding what is labeled as \(y_c\) in the solutions.
Final Exam
The final exam is on Monday, April 29 at 7:00 p.m in LILY G126.
If you are ill and can not come to the exam, you should e-mail me immediately. Do not wait. In the event of this occurring, be prepared to present documentation from PUSH or another healthcare provider. Without this information you will not be permitted to take a make-up exam.
Review guides for the final
Review Problems for Final Exam
Here is a practice final that is available on the main MA 222 webpage. Some of the problems have appeared on old exams, so it's a good source of review exercises. It's much longer than your exam will be, so don't worry if you can't complete all of them within 2 hours.
In addition to reviewing old homeworks (which should be your first priority), you can of course attempt any of the review exercises that I have posted above for exams 1-3. Here are some extra problems for the new material since exam 3 that you may want to consider while studying for the final exam.
- p. 441, #9, 11, 22, 39
- p. 449, #3, 5, 11
- p. 465, #1, 3, 5, 12, 13, 14, 17, 21, 25
Answers to the odd numbered problems are available in the back of your textbook. Full solutions to the even numbered review problems are available here.
Fun problems
Here are some extra problems (with solutions) that in some cases go above and beyond the difficulty level of the homework. They are intended to help better prepare you for exams and are not a replacement for lecture. The rationale is that hopefully if you can do problems that are above the level of the homework, then the exams will be easy for you. My suggestion is to try them on your own first, and if you get stuck consult the solutions.

Polynomial Long Division (via S.O.S. Math) - Useful for some of the homework problems involving partial fractions. Remember: to apply partial fractions, you need the degree of the numerator to be strictly less than the degree of the denominator.
