Topics: (to be expanded later when I have time)
• Inequalities and intervals and interval notation
• Solving absolute value inequalities – Note: We only used the first method given in the textbook for solving the inequalities. (See Example 1.17) This method can also be used for other types of inequalities (and we will be using it later on). Please avoid using the second method unless and until I have time to go over it in class, as many people do it wrong!
Homework:
• Add to or change your email address in CUNYFirst to an address that you usually check.
• If you do not regularly check your City Tech email, here are instructions about forwarding it to another email address, which I also handed out in class. (You can also use Mail.app on Macs, or MS Outlook, to POP or iMAP the emails, if you use either of those two programs already.)
• Register in OpenLab and join this course, using the instructions on the handout. (Or see here.) Registering will give you more access to features in OpenLab. Joining the course means you will automatically be notified when there are new posts, among other things.
• Log in to WeBWorK following the instructions here and start working on the Orientation assignment (at least the first few problems). Then do the other assignment.(This time it is due 11 PM Tuesday, in case there are problems logging in.)
• Please see the First day’s post and make sure that you do or did everything there!
• Routine homework: in Session 1, Exercises 1.6, 1.7 (a)-(f) but skip (e) for now
• Read ahead Session 2
• Warmup for Functions (due 11 PM Sunday): make sure you do the Warm-Up from last time as well! (If you already did it, you should not do it again.)
