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.

Circle 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.

Math 1A: Here is a writeup that can help you with related rates (3.9), optimization and graphing. The step-by-step
processes won't make sense until we cover the corresponding sections. However, you can and should practice the
questions on the first page, about identifying quantities, amounts and units, before the 3.9 lecture on Wed Feb 17.
Math 1A: Here is the updated writeup that can help you translate function and derivative statements from algebra to
English. Make sure you use the correct template for whatever statement you are trying to translate.

You may also submit your graded quiz early.
You can tell which version of the quiz you had by whether the first question asked for a definition or a theorem.
Math 1A: Here's a review package for the first midterm. Questions [1]-[13] involve topics we have already covered.
Questions [3] and [13] also involve topics from section 2.6. Questions [14]-[20] involve topics from section 2.7.
NOTE: The review contains few explicit limit problems (ie. "find the limit of ..."). Instead, there are problems which require you to set up limits, and then find the values of those limits. So, you must know the (calculus) definitions of vertical and horizontal asymptotes, derivative at a point, and instantaneous velocity, all of which involve limits. The last two definitions are in section 2.7. You should memorize them now.

Math 114: Here's a handout which we will cover in class on Fri Jan 22. Print out your own copy (preferably on a color printer) and bring it with you to class on Friday. I will only be bringing a few copies to class myself, and they will be in
black and white, so they will not be as useful as if you print your own in color.
Part of your score will be based on proper writing. Just like in an English, Chinese, psychology or economics class,
if you don't write in the proper notation and structure, you should not expect to get an A.

Math 1A: Here is the cumulative homework list up to section 2.6.
NOTE: For the second question, the key is rounded to 3 decimal places instead of 4. If your 4 decimal place answer rounds off to the 3 decimal place answer in the key, consider it correct.
NOTE: In the third question, just because your final answer is correct doesn't mean you automatically earn full points. Your steps must be correct also.
Here is a sample to show you what is required. Notice that in this sample,
In the second question
she rounded an answer off too much
she got the wrong equation for the tangent line
These are both mistakes, so she did not circle those parts, and she did not give herself any points.
In the third question
she calculated one slope using the reverse order of subtraction in both numerator and denominator
she wrote her work for the averaging of the slopes improperly
The first difference is not a mistake, just another way to do the calculation. The second difference is a writing error, but she feels the work shown is consistent with the correct solution. So, she circled both parts, put an
asterisk next to them to indicate that she knows they're not exactly the same as the solution key, but she feels
they're still valid. And she gave herself the associated points.
She grades in red, so I can tell her grading apart from her original work.
She fills in the subtotal for each question, and the total for the entire quiz.
