How much total drag does my truck create while moving down the highway?
Measure it indirectly!
Run cellphone GPS logger at 1-second interval. Get truck up to speed on flat section of highway, put transmission in neutral, foot off the gas. Let the truck slow down 30 - 45 seconds to get a decent number of data points. Make another data run on same section, but opposite direction to average out effects of wind and any slope.
Import GPS log into spreadsheet.
A linear fit gives you a straight line slope...good enough to determine deceleration...then apply that to F = m * a (you need to know truck's weight) Now you know total drag force at one speed.
Total drag is air resistance (varies with square of speed) plus rolling friction (assume it's constant). OK, do a quadratic/polynomial fit. Now you know rolling friction. Subtract from total drag, and you can determine area-drag (Cd * frontal area) of your truck.

Today I accidentally learned that limacons are inversions of conic sections!
Imaginary numbers aren't just mathematical curiosities. They simplify #trigonometry, #calculus, and #geometry, opening up new possibilities in #math and #science. A mathematician explains: https://theconversation.com/taking-a-leap-of-faith-into-imaginary-numbers-opens-new-doors-in-the-real-world-through-complex-analysis-233965
A few weeks back I was complaining about this meme and we had a good discussion about it on here. I ended up making a lesson plan about taxes and my students really liked it so I will share it. (It is for students with a basic understanding of integration. But, you could probably rework it to skip that bit.)

**The Jagged, Monstrous Function That Broke Calculus**
Solomon Adams
_“Weierstrass discovered a function that, according to Ampère’s proof, should have been impossible: It was continuous everywhere yet differentiable nowhere.”_

university. Her accomplishments were tremendous in her short but astonishing life.⠀
Born Sofia Korvin-Krukovskaya, in Moscow, she attributed her early aptitude for #calculus to a shortage of wallpaper, which lead her father to have the nursery papered with his old differential and integral analysis notes. Her parents nurtured her early interest in #math, and hired her a tutor. The local priest’s son introduced her to #nihilism. So both her bent for revolutionary politics and passion for math

If you've done some #datascience but never really learned or truly understood #calculus, you might find this analogy of interest...
Integration is just split-apply-combine.
Suppose you want to find out the average wealth of people in some state... You could take the data you have, break it up by zip code, calculate the local average wealth estimate, multiply by the number of people in the zip code, and add it all up. Then divide by the total number of people in all the zip codes.
Anyway, here it for anyone who might be interested for education purposes.

Somebody was posting on here about how the various 3D apps handle the X, Y, & Z coordinate system differently recently, and I just spotted the following AMD article that goes into a little more depth on the subject (it's a good matrix math refresher)...

One of the many classes I teach is a calculus course for 12th year high school students. Since their peers are taking Calculus II and Linear Algebra and beyond they regard themselves as “the slow class” which is ridiculous. Most people don’t take calculus until college, if they ever encounter it at all. But young people compare themselves to their peers— 1/
