I also played around with some more mnemonic images. Students often memorize the sines and cosines of 30°, 45°, and 60°. I thought about making a mnemonic image for sin(60°) = √3 / 2, using the decimal value 0.8660 rather than the exact value.
Using the Major system, you can encode 60 as chess or shoes, and 86 as fish. So I thought of a chess board, with a fish wearing shoes standing on it. (Absurd images are easier to remember, and DALL-E excels at making absurd images, though it’s difficult to get it to generate a particular image you may have in mind.)
I was able to generate images of a fish wearing shoes, but when I asked for the fish to be standing on a chess board, it wouldn’t put the shoes on the fish. Here’s the best image I got:
DALL-E images tend to be very large. The original version of the image above was 2 MB. I used Squoosh to reduce the size of the image 98% to produce the image above.
You could make the image much smaller still. I didn’t crop the image because I wanted to show what DALL-E generated, but you could crop it to cut off some of the bottom. You could also edit the image to eliminate the marbling in the squares; solid colored squares would compress much better.
