# Math 252 (Phillips) Midterm 1

## Instructions for remote administration of Midterm 1

Instructions for the remote administration of Midterm 1 are here. Please read them carefully, well before the exam! Changes from the Midterm Zero instructions (pdf) (new text wavy underlined in blue and old text crossed out in red). Reading this avoids repeating old information. (More information.)

## Review session

The review session is Thursday 28 January 8:00--9:00 am (except for the day, at the usual class time), in the usual class Zoom meeting (meeting ID 942 1426 7846). Pdf file of the written work from the review session. (For the link to the video, see the class email message.)

## Sample Problems

There are three primary sources for sample problems for Midterm 1:

• Written homework for Weeks 1, 2, 3, and 4:
• Sample Midterm 1 (pdf).
• WeBWorK homework due through Wednesday 27 January 2021, and WeBWorK extra integration practice problems, through those "due" Thursday 28 January 2021.

Of course, you should also know how to do all the Midterm 0 problems. Note, though, that the Midterm 1 problems will be in format much more like the problems in the first list above. Also, they will be graded by me rather than by a grader, and I will look at work and notation much more carefully than the grader does.

Solutions to items in the list above:

• Written homework for Weeks 1, 2, 3, and 4:
• Sample Midterm 1 solutions.
• Answers to WeBWorK problems are available on WeBWorK after the due date of each assignment.

## Real Midterm 1 Version 1

• Midterm 1 Version 1 (pdf).
• Solutions to Midterm 1 Version 1 (pdf). Corrected version posted about 11:00 pm Sunday 31 January. There are corrections in the solutions to Problems 3, 5, and 10.
• Difference file showing the corrections to the solutions to Midterm 1 (pdf); AMSLaTeX. New material is in red with wiggly underlining; deleted material is in blue and crossed out (occasionally underlined). The correction in the solution to Problem 10 (the last several steps) does not show up.

Reminder: Extra credit will be given for finding mistakes. You need to say what is wrong and how to fix it, you need to be one of the first two people to report the mistake to me, and you need to report it before a corrected version is posted.

not be posted until after it is administered.
• Midterm 1 Version 2 (pdf).

• Difference file showing the corrections to the solutions to Midterm 1 Version 2 (pdf). The difference file has new text wavy underlined in red and old text crossed out in blue. More information. The program did not detect the correction to the limits of integration at the beginning of the last computation in the alternate solution to Problem 10.

Reminder: Extra credit will be given for finding mistakes. You need to say what is wrong and how to fix it, you need to be one of the first two people to report the mistake to me, and you need to report it before a corrected version is posted.
