Math Help: If I have a nonlinear transformation T: R^m -> R^n, what do I call the set of solutions to T(x)=0? Is it just roots or zeros? Or is there a fancier name for it?
Hear me out:
Instead of multiple classes meeting 3-4X a week for 15 weeks. One class meets 3-4 hours per day (2 hour morning session + 2 hour afternoon session) for 15 days.

Been seeing lots of @Desmos 3D discussion around surfaces of revolution for Calculus. While parametrics are great for showing the act of rotation (see: desmos.com/3d/1a7f86ac77), I'm also loving this strategy, accessible to students who have seen equations of circles before:

Just finished #GradingForGrowth. If you are even remotely interested in the alternative grading movement, I highly recommend it. Even if you’re not, it might change your mind.
Friends in academia, let this serve as a reminder that a promotion without a significant raise isn’t a promotion, it’s a title change.
Also, promotions come with a shift in responsibilities, not only more responsibilities.

It’s only a matter of time before students are able to work a problem, scan it, and have AI leave feedback and grade their work.
I wish that day was today.
