This folder contains the Mathematica notebooks I wrote while writing lectures for MATH 127 in fall, 2017. After a single introductory lecture, the course was divided into five blocks: Functions, Limits, Derivatives, Applications of Derivatives, and Integration. The folders reflect this organization. Later notebooks are named according to a consistent scheme -- for earlier ones I was not quite consistent. When I wrote these notebooks, I was really only aiming to produce things that were useful to myself, so they're not typically well-explained or well coded. You'll probably find them easier to understand with the help of the corresponding Powerpoint presentations. These can be found on the Learn site for MATH127. I'll move them here in some form once the course has ended and Learn turns off.
