This page details what I've been working on lately, so that you can find recent changes to my site. It's entirely possible that some links on this page shall fail to work, or fail to live up to their descriptions: that just means I haven't checked in (recent changes to) the pages they referred to as recently as I've updated this page. This page omits things separately covered by the thoughts of the moment section of this site, unless I update one after its moment: this page is about on-going development on the rest of this site.
Explored the gradients of chords to show how an algebraically formulated deriviative matches my latest reformulation of how to do differentiation. Explored several other details (e.g. multinomials, particularly homogenous ones) in support of that.
Began describing one of the tools that shows up repeatedly all over mathematics.
