Reading: Read section 1.6. Use the accompanying pdf note pages to document your
understanding of the terminology which formalizes some of the ideas
we've been looking at in 1-4 and 1-5. The first few rows are terms
you know from previous sections, but most of the rest is discussed
and clearly defined in section 1-6.
Video: Watch the following Kahn Academy video on
concavity and slope. This highlights what we will be looking at in
the next few sections. The first 2 minutes are review of what we
have already discussed about concavity, but the next 8 minutes
introduces some important ideas. It might be best to stop at 10
minutes and then we'll return to watch the last 3 minutes when we
get to section 1.7.
