Could be as trivial as a type of food, a TV show, or something more serious.
Yeah, a lot of math education teaches memorization. This isnt math. If you can understand how a formula was derived, rather than just memorizing the formula, I find it a lot easier to remember. I’m not really memorizing a formula exactly, rather I understand better of how I get from what I have to what I need.
I agree, my highschool often just stated mathematical equations without explaining what they were. They told us you find the sidelength using sin and gave js a formula and thats it. They didn’t say what sin actually was/represented, how to calculate by hand or even show us the classic unit circle like on this website https://www.mathsisfun.com/geometry/unit-circle.html
