MTH-130 Precalc: Remaining HW Assignments

Here are the rest of the homework assignments for the semester.

By 11/16 you should have completed the following:

4.5 Vocab Check and #5-25 odd, 31-59 odd
4.6 Vocab Check and #9-37 odd, 49, 51

Due to the Thanksgiving holiday, you've got two weeks to complete the remaining assignments, which should be done by 11/30. These are as follows.

4.7 Vocab Check and #5-19 odd, 43-47 odd, 55-65 odd, 69
4.8 Vocab Check and #5, 9, 15, 19, 21, 27
5.1 Vocab Check and #11-15 odd, 23, 25-51 odd, 71, 75, 81
5.2 Vocab Check and #9, 11, 13

We will discuss these four sections in class on Friday 11/16. Then get right to work on it, since you'd rather know sooner than later that you need help.

There is an additional assignment in the syllabus, which I don't require but you might as well do: Review, pp. 364-6, #43, 57, 65, 85-91 all, 95-101 all, 103, 111-114 all, 123-127 all, 140.

So you can keep it for studying, this fourth batch of homework is due the day of the final exam, 12/14. It will be worth five points like the other assignments, and I'll give you 6 points for completely working out all the assigned problems in 4.5 through 5.2 plus the review exercises. As usual, you can also get extra points for neatness, so be neat. You're not just helping the person who has to read it; you're helping yourself, too!

We will review for Test 4 on 11/30, so there will be a practice test posted on this blog at least a couple days before that. You should print out the practice test and make yourself do it as if it were the real test, in order to find out where you need more practice. Then bring your copy of the practice test to class on 11/30.

There will be an announcement soon regarding Test 4, in class on Friday and here on this blog.

Math 130 Practice Test 3

Here is practice test 3. Print it out, and try to work the problems as if it were the real test (no book, no notes, no calculator). This will tell you where you need more practice. Then bring it to class on Friday.
The answers follow after the break.

MTH-130 Test Announcement

As announced in class previously, Test 3 will be in the Test Center 11/10-11/16. We will review for the test on 11/9. Check back here for the practice test.

Here is the practice test we'll go over on Friday, October 19.

The answers are below the break:

HW for Diff Eq's Assigned 10/15/12

We moved on to differential operators (Section 4.5) and the annihilator method of undetermined coefficients (Section 4.6). The homework for these sections is as follows:

Section 4.5: #1, 5, 9, 11, 21-31 odd, 35, 37, 39
Section 4.6 #1-21 odd, 33, 35, 37

Section 5.1: #1, 15-18 all
Section 5.2 #1, 15-17 all
Section 5.3 #2, 3

These all cover simple harmonic motion (5.1: free undamped, 5.2: free damped, and 5.3: forced). Section 5.4 will cover other applications of linear 2nd order DE's with constant coefficients, mainly LRC circuits. There will be problems assigned from this section later.

MTH-130 Precalculus Test 2

The test I announced last week is postponed. We will have the test review on 10/19 and the test will be in the Testing Center from 10/20 to 10/26. The Chapter 2 homework will also be due on 10/26. Check back here for the practice test.

Section 2.3, pp. 156-158: Vocab check and #7, 11-15 odd, 27, 29, 37, 47, 55-61 odd, 67, 69

You should definitely try to do all this homework by Friday, and seek help with anything you really don't understand.

MTH-130 Precalculus Pretest

Here is the practice test for you to print out. The actual test is very similar. Try to do the test on your own and bring it along to class on Friday. As announced in class last Friday, the test will be available in the testing center at Mt. Laurel from Saturday, September 22 through Friday, September 28.

MTH-230 Differential Equations Homework

Here's the homework so far. I said it would be all the homework for Test 1, but we might have a few applied problems from Chapter 3 as well.

MTH-130 Precalculus Homework for 9/14/12

Finish doing the previous homework, up through Section 1.7. We'll go over it on Friday (9/14).

Here is the homework for Sections 1.8 and 1.9. Try to do these problems before Friday.

1.8: Vocab check and problems 9, 17, 41-47 odd, 53, on pages 88-91.

1.9 Vocab check and problems 7-29 odd, 39-43 odd, 49-53 odd, 87, on pages 98-101.

MTH-130 Precalculus Homework for 9/7/12

Here is the homework you should do by this Friday. It's a lot, but it breaks down as follows. Sections 1.1 through 1.3 are review and we covered them in class, so they shouldn't present much trouble for you. Just do it; it's good practice and should be a confidence builder for you. Section 1.4 we also covered in class; I expect you to get through all those exercises as well. Sections 1.5 through 1.7 we did not cover in class at all; these would normally be assigned for Week Two. Attempt these problems anyway. If you can do all these problems, great! If not, it should get you started asking questions (even if they start with "What the...!"). As long as it isn't something dangerous like scuba diving, it's good to attempt it on your own before your instructor explains how to do it. That way you are motivated to overcome frustration and you come to class with some expectation of what he'll be talking about. (You don't have to wait till Friday either--you can email me as soon as you run into trouble.)

Here is the homework assignment:

Section 1.1: Vocab check and exercises #27, 41, 47, pages 8-12.
Section 1.2: Vocab check and exercises #7, 19, 25, 33, 35, 49, 68, 71, pages 21-23.
Section 1.3: Vocab check and exercises #17, 19, 31, 45, 83, 87, pages 33-38.
Section 1.4: Vocab check and exercises #7, 9, 15, 19-23 odd, 37-49 odd, 53, 59-65 odd, 71-81 odd, 103-107 odd, pages 48-53.
Section 1.5: Vocab check and exercises #9-13 odd, 17-31 odd, 39-45 odd, 83, pages 61-65.
Section 1.6: Vocab check and exercises #11, 21-27 odd, 43, 45, 57, 59, pages 71-72.
Section 1.7: Vocab check and exercises #7, 15-61 odd, pages 78-82.

MTH-130 Precalculus First-Day Handout

MTH-130-500 Precalculus                            Instructor: Edward Bailey (ebailey@bcc.edu)

Friday 05:00PM - 08:45PM, Laurel Hall 207                                             http://mathematikoi.blogspot.com

Course materials: The syllabus and textbook (Precalculus: A Concise Course by R. Larson) are available at the bookstore.

Attendance: You are expected to attend all class meetings. Showing up late or leaving early does not count as attendance. If you miss a class, you are responsible for obtaining missed class notes and assignments. Whenever possible, please let me know ahead of time if you are going to miss a class so I can let you know what work you will need to make up.

Conduct: Students are here to learn. Any conduct that your fellow students would reasonably find distracting will be cause to remove you from the classroom. Examples of such misconduct include side conversations, texting, and sleeping. As your instructor, I am focused on the students who are actively engaged in learning. If other students are engaging in conduct that you find distracting, do not hesitate to bring it to my attention and I will deal with it promptly.

Homework: All homework for each unit must be submitted on the day of the unit test. It must be stapled together. Loose pages will not be accepted. Put your name, the section numbers, and problem numbers on the homework, so I can tell what and whose it is. It will be graded for neatness and completeness.

Calculators: The course catalog calls for a graphing calculator, such as a TI-83. However, any ordinary scientific calculator is sufficient for this course. What students need from this course is understanding of the material and ability to apply it, without which the calculator is useless. You should also not expect a calculator to do anything you can’t do, given time. Therefore, to the extent possible, calculator use will be prohibited on tests and quizzes.

Unit Tests: Unit Tests will be given as announced, with a week’s notice.

THERE ARE NO RETESTS

Final Exam: A comprehensive final exam will be given during finals week.

Office Hours: I do not have an office. However, I can arrange to meet with students on before class. Email me and I’ll try to get back to you promptly. Email is the way for you to contact me outside of class. Use your BCC email account so your email is not mistaken for spam. Also, check my blog for announcements (see above).

Grading Policy
Homework: 10% Quizzes: 10% FOUR UNIT TESTS: 16% each Final Exam 16%	Final grade as a function of overall average x. x ≥ 90% = A 85% ≤  x < 90% = B+ 80% ≤  x < 85% = B 75% ≤  x < 79% = C+ 70% ≤  x < 75% = C 60% ≤  x < 70% = D x < 60% = F
At the instructor’s discretion, a “fudge factor” may be applied to a student’s grade. It will take the form of points added to the final percentage grade. Under no circumstances will points be taken away. The reasons for adding points to a student’s grade include attendance, class participation, coming to class prepared, and other indications of effort and positive attitude.

"X" Contracts and Incompletes: There will be no “X” contracts or incompletes. The last day to drop (with a 50% refund) is September 12. The last day to withdraw is October 26.

Diff Eq's: Solutions to Problems in Section 4.4

Here are solutions to problems #1-17 odd in Section 4.4 where we solve non-homogeneous linear DEs with constant coefficients, where the forcing functions are sums and products of polynomials, exponentials, and sine and cosine. The last few involve a great deal of bookkeeping to determine the coefficients.

Note that in #15, the forcing function has the same frequency as the natural frequency gotten from solving for the complementary solution. Therefore, you might have guessed the particular solution to be of the form x(A cos ωx + B sin ωx), but if you tried it, you found it didn't work. It would have worked if the forcing function weren't already multiplied by x. Since it is, we must instead propose a particular function with both sine and cosine multiplied by 2nd order polynomials with undetermined coefficients. (Actually, you could always err on the side of caution and propose higher order polynomial multiples. That would be a lot of useless busy-work, though, in cases where we can be sure of the order of the polynomial in the solution.)

Since you made it through Calculus III, you should be well aware that diligence in doing homework assignments is the key to success.
Calculators: Use of calculators on tests is neither necessary nor permitted.
Office Hours: I do not have an office. However, I can meet with students on campus on Mondays and Wednesdays after class. Email me and I’ll try to get back to you promptly. Email is the way for you to contact me outside of class. Use your BCC email account so your email is not mistaken for spam. Check my blog for announcements (see above).

The test will be on Wednesday, April 18. We will review for it on Monday, April 16. Here is the practice test. This is not the multiple choice version. Hopefully I will post a multiple choice version soon, but not until after proofreading the actual test and sending it off to the print shop. Before Monday, try to do all the problems on the practice test so you know what problems you have trouble with. Then you'll REALLY pay attention to the review.

MTH-075 Homework for Monday, March 26 (and beyond)

I put off collecting homework for Sections 5.4, 5.5, and 5.6 on Wednesday. This is now due Monday, March 26. The assignments for these sections are given in the syllabus, as always.

We covered 5.7 and (admittedly in haste) 5.8. This homework should be done by Wednesday, March 28 (the day of the test review). Don't forget there's a test coming up!

For extra credit, you may submit the Review Assignment for Chapter 5, which is also in the syllabus. (The sample test it refers to is the one in the back of the syllabus.) This may be turned in the day of the test.

If you are unable to attend class, you should email me and ask what you're missing. You can also scan your homework and send it as a compressed image file--that counts as turning in homework. And remember, I don't give a hoot if you get the right answers on the HW: just show your work. Do your thinking on paper!

MTH-095 Practice Test #3

Here's the practice test without multiple choice answers. It does, however, have the correct answers at the end. I'll add in multiple choice and post the updated practice test tomorrow. Just remember: if you know the correct answers when you see the multiple choice version, it won't be like the real test, so my advice is don't look at the correct answers yet.
