Math 251 (Phillips) Week 4 schedule and information

• Monday 27 January:
  • Quiz 1 (9:00 am) (corrected).
  • Quiz 1 solutions (9:00 am) (corrected). Corrections not sufficiently proofread.
  • Quiz 1 solutions (9:00 am) (differences). New material in red; old in blue. The correction of t to y in the solution to Problem 1 doesn't show up.
  • Quiz 1 (11:00 am).
  • Quiz 1 solutions (11:00 am) (corrected). Corrections not sufficiently proofread.
  • Quiz 1 solutions (11:00 am) (differences). New material in red; old in blue.
• Tuesday 28 January:
  • Written Homework 4 (pdf) due in class, on paper.
  • Solutions to Written Homework 4 (pdf). Not enough proofreading has been done.
  • Worksheet used in class.
  • Solutions to the worksheet used in class. Minor nonmathematical changes have been made, and the misprint on the 9:00 am version has been fixed (the correct dreivative of cos (x) is - sin (x)).
  • WeBWorK assignment NCP_2025W_W4D2 due, 9:00 pm. In Problem 2, the domain isn't a closed bounded interval, hence the instructions to find the minimum by graphing. (We will learn the right way to do this in several weeks.)
• Wednesday 29 January:
  • Worksheet used in class.
  • Solutions to the worksheet used in class.
  • Review session, 8--10 pm, 110 Fenton. The building might be locked. If so, go to the door on the south side of the buiding (facing 13th Avenue) and, if it is not open, knock loudly. I expect to have a worksheet. If I run out of copies, the room is close enough to the department office for me to print more.
  • WeBWorK assignment NCP_2025W_W4D3 due, 11:30 pm. (Later due time to avoid conflict with the review session.)
• Friday 31 January: Midterm 1 (in class). (Nothing else will be done in class this day.)
