E-mail Subject Line: Math 104 Your Name 3/25

Reading Questions:

Suppose that 0 < f(x) < g(x).
1. If int(f(x), x=1. .infty) diverges, what can you conclude about int( g(x), x=1. . infty)?
2. If int(g(x), x=1. .infty) diverges, what can you conclude about int( f(x), x=1. . infty)?

Reminders:

• Bring remaining questions on PS 7 to class Monday.

2. Does l'Hopital's Rule apply to lim_{(x -> infty)} x² / sin(x) ? Why or why not?

Reminders:

• Look at PS 8.
• Exam 2 is next Tuesday. Make a study plan, and again allow at least 8 hours (even if it turned out you didn't need that long last time -- the material just keeps getting more complicated!).
• The rough draft of your project should be well underway by Wednesday.

Friday 3/29 at 8am

Section 10.4: l'Hopital's Rule: Comparing Rates

No Reading Questions today (unless you never did the reading questions for Wednesday, in which case you should send those on in for half credit!)

Reminder:

• The time and day of the help session has been changed to Sunday at 6:30pm.
• If you missed the deadline for full credit on the antidifferentiation exam, you have until Monday (April Fools) to at least get 80% on it.
• Remember to make the time to come to my office hours!
• Project 2 is due Friday at 3pm. Once again, I urge you to bring in a rough draft beforehand, and to have a friend who is not in this class (and preferably, who is not familiar with Calc 2) read through your letter to see whether they can understand the situation, and whether they find your solution convincing, not confusing, and not too dry.
• Get a start on studying for that exam!
