In Oklahoma, the requirement usually is up to “algebra 2” - this is mostly domain and range, finding roots of polynomials, and logarithms.
IMHO, the world would be better if calculus was a required part of the high school curriculum. Like yeah, most people aren’t going to need the product rule in day to day life, but the fundamental ideas about rates of change seem like they’re something that everyone human deserves to be exposed to.
I remember trying to figure out if a specific infinite sequence converges or diverges because I was playing Sonic. I didn’t have any algebra nor calculators that could handle precise calculations nor the terminology I refer to it as now, so I was just trying to guess by doing calculations by hand to see if it looked like it was plateauing to something or if it looks like it was gonna keep growing.
Not sure if its actually useful, but it was something I cared about regardless. Children should play with math more.
