Questions, errata, and all that
As you have probably noticed, there are a lot of advantages of on online video seminar compared to a traditional classroom. At the same time, there are also a lot of disadvantages. In a classroom, I can see your reactions and use that to find out when people are confused. I can’t do that online, so you need to be more aggressive about asking me questions. In a classroom you can also benefit from other people’s questions, but it is harder to do that online when you can’t hear each others questions. One way that I am trying to overcome that problem is to update the files in response to your questions. For example, I added some alternate solutions to A.4 # 4 in response to a question about the problem.
I am also correcting mistakes as people point them out to me. This means that if you find a mistake in a .pdf file, then I probably don’t yet know about it. Please let me know about these mistakes as you find them even if they seem minor to you so that I can fix them. The most important corrections will be included in the errata page.
As a final note, don’t forget that the solutions to the problems are available on our alternate sites tiavideos1 and tiavideos2.
