We will begin with Q & A. You should be done with substitution at this point; if you come in with questions, but have not asked them in advance on Piazza, I will likely not answer the question. Put another way: you will have had almost 2 weeks with the material—there should be no questions of substance the day after things are due, unless you asked previously and still do not understand.
I will then provide some context and forward-looking material regarding functions and their relationship to with. Substitution (and how it does and does not work) will factor heavily into our preparation.
See Tuesday, O25 for what is due upon arrival to class. Specifically, a discussion of how substitution works. (I pulled this out of the previous assignment and aimed to keep it separate.)
