It sounds like it's machine-scored, which is unfortunate. A teacher seeing this would have a convo: "Wow! That's an interesting answer! What's the def of a multiple? If we look online, we see some say N*(integer) and some say N*naturalnumber. Which def seems most useful?"

Looking directly for a pentagon is hard; looking for a ring of 5 is easier!

"The average IQ in Somalia hovers around 70, and that's the threshold for mentally handicapped ... they're a net drain on the society" -- even by MAGA standards, the unvarnished racism of this interview of Rep. Brandon Gill by Benny Johnson is breathtaking

Here's (I hope) an animated GIF.

Rolling Quarter

Working on a piece about polar coordinates, and reminded of the "rolling quarters" cycloid by @tenorfrank.bsky.social, I built this little @desmos.com animation. #iTeachMath www.desmos.com/calculator/d...

There is very little publicity about this - it just does not seem to have the mindshare - at least atm - that the last No Kings did. And it requires more energy and commitment than just showing up on a Saturday morniing. I fear it will be underwhelming.

I used LaTeX Overleaf with my MultiCalc groups every year and had a similar experience to yours. “It’s so satisfying!” said one! And I had good feedback about it from alums who used it in college for assignments.

Btw, MathPix can be a useful tool.

Two lovely (but slightly different) curves with five-fold symmetry, one generated via complex function and one by a parametric function.

Thanks for this! I got a used copy and have started reading. It's a wonderful blend of pleasing visuals and elegant math.

I'm using Desmos to draw the curves. Here's two early examples, one complex and one parametric.

I always titled my formula sheet as "Possibly useful formulae".

Maybe include one oddball on each test :).

New York Times and WSJ editors continue to trivialize massive pro-democracy demonstrations. Analysis of "No Kings 3" front pages. Local editors continue to shine. New York Times and Wall Street Journal leadership continue to downplay and minimize mass demonstrations while editors of smaller outlets do a better job communicating these vital pro-democracy events.

The influential @nytimes.com @wsj.com continue trivialize the pro-democracy movement & #NoKings mass demonstrations.

Good news: editors of local outlets continue to shine.

100%. On a daily basis I think “The founders did so much right, but they really blew it with the pardon power! What were they thinking!”

Can no one do anything about this grift and theft?!?

Analytic Geometry: Descartes YouTube video by The Random Professor

This is cool! When I was in HS I found Descartes work - adding, multiplying, etc., lines and spent a happy afternoon in the library recreating/understanding it. You might find this video of interest: youtu.be/G24Y8Bb-NAA?... The whole thing is iteresting, but the link starts at multiplying lines.

This is great! Note: At least for me, it loaded slowly and I almost gave up on the first screen. Patience will be rewarded! #iTeachMath #mtbos

I taught APCalc before e-d was removed and after; I kept it in my curric even after. However, we should not overestimate the understanding of e-d of Calc1 students, and it is quite difficult to assess this understanding on a standardized AP test. It was usu. just a pattern-vulnerable MCQ or two.

..it's now safer to teach to the test and hope that understanding follows. The exam and curric are reasonable but results now often tell more about test prep than understanding.

There are lots of exceptions to this negative picture, and all AP Calc tchrs deserve praise for fighting the good fight.

The test has existed since 1956 in roughly the same form, and past exams are available. Naturally, classes have evolved to optimize test scores. Where once tchrs tried to teach the best Calculus course they could, ing trusting that good scores would follow,...

Asked about paying for child care, Trump pivots to tariffs YouTube video by Washington Post

Don't I recall that during the campaign he was asked about child care and he said tariffs were going to bring in so much money that it would be easy to do?

Here it is: youtube.com/shorts/XCzF0...

Thanks for this.

TIL: A German colloquialism for "quadratic formula" is Mitternachtsformel which translates, literally, to "middle-of-the-night-formula". That is, a formula which is so deeply memorized that if awakened in the middle of the night, the student could recite it. #iteachMath #MathsToday

Nice. How about adding "What's the *maximum* number of lengths that can be provided but still not allow the area to be found?

I would say "All angles are right" rather than "two rectangles" (better would be to mark them). And if I were using this with Ss, I would leave off the choices and just invite them to solve the problem and share their methods. Maybe you'll get lucky and there will be a wrong answer to learn from!

As a NYS student in the 70s, my friends and I recognized that to achieve success on the History Regents exams, one had to turn off critical reasoning and put ourselves in the mind of the narrow-thinking functionaries who wrote the test.

It's also useful to point out that, for example, if the inner function is ax, it causes a horizontal compression by a factor of a, so the integral (area) result will be smaller by a factor of a.
