I assume this is an implicit differentiation question, with w, q, and z functions of t. In which case, you might want to use the chain rule.

That was a good hint. Also, "abecedarium" is my new favorite word.

Well now I need to wait for this to come to streaming so I can do that. As long as I can figure out how to keep popcorn close enough to my treadmill.

Nope, Calculus 1 and Abstract Algebra. Real analysis would be a lot of fun though.

I was thinking QUBES hub as well.

I'm not looking to rank courses. I'm hoping to find well written learning targets to help me build my specification-based grading course. And hopefully help other instructors do the same. Writing good, assessable learning targets is hard!

I tried to capture some of the advice from a seminar by an accessibility expert as part of the PreTeXt guide. See Subsection 4.40.3: Advice for Writing Image Descriptions

The easiest way to use pandoc for pretext is to use the feature in vs code and pretext-tools. Assuming you have pandoc installed, search for the command pretext: convert file to pretext.

There are currently too many conversions in pretext-tools. I need to clean that up.

Are we sure we aren't living in Fight Club? Or am I not supposed to talk about that?

I hear, "Happy Easter to those who celebrate it. And to everyone else, enjoy celebrating Hitler's birthday."
