Lesson 21a.

NOTE 1: Be sure to read Homework Format and Homework Writing Policy BEFORE writing up your solutions to be turned in.

NOTE 2: When two or more Lessons are to be turned in on the same day, please staple the Lessons separately and turn them in separately.

Due Monday, March 3

Sect. 5:
See Set Builder Notation in the Set of Real Numbers and do Problems 3 and 4 there.
(As usual, if you have previously done these problems correctly, you can turn in your previous work, as long as it is clearly marked for this Lesson and it is easy to grade (for example, but not necessarily, copy and paste.)

NOTE: As stated on the Course Home Page, all due dates are tentative. Assignments, or parts of assignments, may be postponed to a later date.
