Dear class:

Tuesday is the final class and we will talk about 
the Improper integrals (8.6).
We'll only give very dhort introduction on (8.5).
No class on Thursday.

As a practice for the techniques of integration
(8.2, 8.3 and 8.4), I suggest you practice on the 
problems on 

page P554: 129, 131, 133, ... upto 193.

These problems  are ordered randomly, mixing the
techniques in 8.2-8.4 together.
Do as many problems as you can.
You can find the solutions for these problems at the
back of the textbook.
Tuesday evening is the final class of problem session,
if you still have difficulties on these probelms 
(or other parts), you can ask the TA then.

You don't need to give these homework problems to the TA.

Best,
Weicheng
