(turn the graphs on to see!)
the sine "difference of squares" is more fascinating, but tinkering to find the cosine identity was fun, too

Thinking about how Bluesky has a setting that requires you to put alt text on pictures. (You should turn it on!)
A fun activity in math class might be giving the students a mathematical image or graph and ask them to write the alt text. #MTBoS #iteachmath
(Should it be #MBBoS?)
