A fun little scroll-driven thing I made. The text is white over the image, but the image isn't static, it rotates on scroll. 
Here's a detailed explanation of the how behind https://www.reddit.com/r/css/comments/1jyu76v/comment/mn2fibt/

Also uses container queries, CSS trigonometric functions.
Saw a @codepen demo using... a lot! of elements (screen 1) and quite a bit of #CSS to create a simple loader, so I forked it and made a 1 div version (screen 2) in under 30 CSS declarations (gradients, mask, variables to only change --c0 and --c1 values for 2nd loader): https://codepen.io/thebabydino/pen/PwoLJLR

Same result, just not writing almost the same `text-shadow` a bunch of times in a bunch of keyframes.

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
Used the laser cutter to make a holder for my class set of spirographs — for the lessons I like to do my students need to know how many teeth the gears have. They write a program that produces the same curve using turtle. (with older students we do the trig, which I just call “magic circle functions” for the grade fives)
This will make it all go much smoother!
This is 8 sets packed into one box!

Love Triangle: How Trigonometry Shapes the World by Matt Parker, 2024
Trigonometry is perhaps the most essential concept humans have ever devised. The simple yet versatile triangle allows us to record music, map the world, launch rockets into space, and be slightly less bad at pool. Triangles underpin our day-to-day lives and civilization as we know it.
#tinyCSStip Want to create a triangle with all edges equal in 4 simple #CSS declarations?
Such a triangle also has all vertex angles equal = (sum of angles in a triangle)/3 = 180°/3 = 60°
Knowing its edge length a, its height is a·sin(60°).
Aspect ratio of the box
a/(a·sin(60°)) = 1/sin(60°)
#HighSchool #students who came up with 'impossible' proof of #PythagoreanTheorem discover 9 more solutions to the problem
In a new peer-reviewed study, Ne'Kiya Jackson and Calcea Johnson outlined 10 ways to solve the Pythagorean theorem using #trigonometry, including a proof they discovered in high school.

Two teenagers have once again proved an ancient math rule.
From Science News: “Some people have the impression that you have to be in academia for years and years before you can actually produce some new mathematics,” says mathematician Álvaro Lozano-Robledo of the University of Connecticut in Storrs.

I think this is a #Geometry #Joke but it might be #Trigonometry Joke all I know is I laughed.
trigonometry: three gnomes in a trechcoat, measuring things.
Old news with a current news twist:
"Two high school students have proved the #Pythagoreantheorem in a way that one early 20th-century mathematician thought was impossible: using #trigonometry.
Calcea Johnson and Ne’Kiya Jackson, both at St. Mary’s Academy in #NewOrleans, announced their achievement last month at an American Mathematical Society meeting."
The twist:
the #basketball legend #CharlesBarkley gave their school $1M for it
The problem with trigonometric identities is that there are so many to choose from.
People who are good at maths, please help!
Adam is trying to divide a circle into three equal parts using two parallel lines. The total area of the circle is 5027sq mm so he needs to know where to put the dividing lines so that each section is a third of that area (ie 1675.67 sq mm)
We have looked this up but it requires a higher level of maths than either of us are capable of without spending an entire day revising everything we ever learnt about trigonometry (assuming that's what you need).
Thanks for any help you can offer, from us, two maths-challenged creative types ;)
Teens come up with #trigonometry proof for #PythagoreanTheorem, a problem that stumped #math world for centuries
A #highschool teacher didn't expect a solution when she set a 2,000-year-old Pythagorean Theorem problem in front of her students. Then Calcea Johnson and Ne'Kiya Jackson stepped up to the challenge.

That is awful.
I got into legal trouble the last month of high school and happened to also be failing #trigonometry.
I found out the teacher was talking shit about me to other classes.
I confronted her about it.
She said I needed to focus on trig.
I said I didn’t need it to graduate.
I later passed trig in college and also earned a degree in #engineering.
Fuck gossipy, doubting teachers!
