desmosでほとんどDAWみたいに曲を奏でることができるようになった!これからは数式で作曲の時代や! desmos.com/calculator/vsc…

数学よわよわすぎてこいつの行列見つけるのに2時間かかった 黄金比が出てきたとき?!?ってなった けど作りたかった物が作れて満足 desmos.com/calculator/qqj…

二次曲線(円錐曲線)は5点あれば一意に定まるの図。 このとき4点を固定して1点を動かして得られる二次曲線群の「中心」もまた二次曲線を描く。 この二次曲線は4点に対する九点円錐曲線と一致する。 焦点の軌跡も描いてみると、複雑な曲線になる。

I feel like I haven't posted much in a long time so here's a graph from 2 years ago: desmos.com/calculator/kxl… Basically you take a segment with a bump in it, shift every point forward a distance of 1 in the tangent direction, and make the result the next section of the curve.

And to think…it’s somehow even more beautiful in real life. #EarthDay 🧵Why we loved these Art Expo submissions 👇

Have a graph idea that's outside of the box? Add variables to the definitions of your graph bounds to track a point along a curve, adjust the window using actions, keep a label in the same relative position on your screen, and more. The possibilities are boundless. #iteachmath

made a puzzle: Place the digits 1-9 once in every row and column. 3x3 boxes may contain only 3 distinct digits, each repeating 3 times. A digit in a circle indicates the number of circles that contain that digit. desmos.com/calculator/lhu… logic-masters.de/Raetselportal/…

Place the digits 0-9 into every row and column without repeats. Any 3x3 square of cells cannot contain repeated digits. Digits along arrow sum to the circled digit. Grey circles must contain odd digits. sudokupad.app/rr0c3hgcmk logic-masters.de/Raetselportal/…

Have you noticed a change of colors? 🍂 You can now define colors in the 3D calculator that depend directly on coordinates. 📝Learn more in the Desmos Help Center: help.desmos.com/hc/en-us/artic… #desmosart #colors #iteachmath
