In 1897, Dr. Edwin Goodwin got the Indiana House of Representatives to unanimously pass a bill which would have effectively pegged the
value of Pi at 3.2, 3.23 or 4.
Math 1B: Here are the review packages for all the midterms, plus one last package for the post-midterm 3 material.
In addition, you should photocopy many integration problems from the integration techniques sections, cut them so each question
is on a separate slip of paper, and toss them together in a pile. Then, one at a time, draw a random question from the pile,
and do it. Use problems from the assigned and unassigned exercises, the examples, and the chapter review.
There will be multiple versions of the quizzes, but all questions which may appear are given above. Each quiz will contain about half of the questions listed.
Math 1B: Midterm 3 consists of only 2 types of problems: definite and indefinite integrals using any integration
technique discussed in sections 6.1 to 6.5 (or 4.6 substitution), and probability questions.
For the integration problems, you should photocopy many integration problems from each section, cut them so each question
is on a separate slip of paper, and toss them together in a pile. Then, one at a time, draw a random question from the pile,
and do it. This will give you practice trying to figure out quickly what technique to use when you have no hint what section
the question came from. Use problems from the assigned and unassigned exercises, the examples, and the chapter review.
Here is the review material for the probability questions only.
Math 114: For those who missed it in class yesterday, here is the handout for finance problems. The five

Math 1B: Here are the solution keys to use for grading Quiz 4.
You will pick up your ungraded quizzes on Wed Oct 28.
Do your grading using a contrasting color - red, green, purple etc., not blue or black (so I can tell your original work from your grading).
Underline the parts of your work that correspond to the points on the solution key, and the number of points each part was worth.
If some step(s) of your algebra is/are different from the key, but still correct, put an asterisk * next to the points for that part.
Write the number of points you earned for each question in the SCORE: area to the right of that question.
Write your total score for the quiz in the SCORE: area on the upper left corner of the front side of the quiz, just beneath the date.
Your graded quizzes are due in class on Mon Nov 2. No late quizzes will be accepted.
You may also submit your graded quiz early.
The versions differed in the first question (either volume, or definition).
There will be multiple versions of the quizzes, but all questions which may appear are given above. Each quiz will contain about half of the questions listed.

Page 1 tells you how to figure out which direction to cut a region that is revolved about an axis.
Page 2 tells you how to set up the integral for solids created by revolution or solids with fixed shape cross sections.

Math 1B: Here is the code for the numerical integration program (INTEGRAL) for your TI-82/83/84/85/86 calculator.
It calculates left hand, right hand, trapezoidal, midpoint and Simpson's Rule sums.
If you have a TI-83/84, I can copy the
program from my calculator to yours in class tomorrow or during office hours. Otherwise, please type the code into your
calculator. You will need it for Midterm 1.
There will be multiple versions of the quizzes, but all questions which may appear are given above. Each quiz will contain about half of the questions listed.

Your graded quizzes are due in class on Wed Oct 7. No late quizzes will be accepted.
You may also submit your graded quiz early.
The versions differed in the first question (either find an average value, or simplify a sum of integrals). There was no difference in the no-calculator section.

Math 114: Here are a couple fully explained examples if you're having difficulty with the additional homework
assignment about radical equations (see tue sep 29 entry below).
Math 1B: Here are the solution keys for Group Quiz 1.
I graded this quiz for you, identifying your errors, but you should look carefully at the mistakes you made so you can reduce your likelihood of
repeating them.
The versions differed in the function under which you were asked to find the area (either 3x^2 - 6x + 5 or 3x^2 - 4x + 3).
Here are alternate solutions that take advantage of the similarity between the left hand sum and the right sum. The method is a little easier
algebraically, but there is an error that you could very likely make and wind up with the wrong answer.
There will be multiple versions of the quizzes, but all questions which may appear are given above. Each quiz will contain about half of the questions listed.

In this sample, the student's algebra was different in several places, but still correct, so s/he marked all the
corresponding points with asterisks *.

Math 114: I will be adding an extra quiz to the quarter. That quiz will serve as your makeup quiz if you can't take this Thursday's quiz on 6.5.4 and 11.1.1 for any reason related to setting up your Enable account (eg. financial).

Math 114: As it turns out, wireless access is only available to PSME division machines in the S4 building. You won't be able to connect your own laptops in our labs.
I am working on an alternative, since there are currently more students than machines
in S44.
Also, a reminder that you lose points for lates and absences (according to the spreadsheet) starting Mon Sep 28. (No points will be deducted this week, while you get used to the procedure.) FYI, the clock on my laptop is synchonized with the clock in the classroom.
