| Apr 1, 2023 at 0:45 | comment | added | guest philosopher | Also, FWIW, I'm actually more a fan of learning the algebra /calc (just equations) first and then mastering it and only attacking word problems (which are "hard" later). But you at least allude to how max/min is often econ driven. | |
| Apr 1, 2023 at 0:45 | comment | added | guest philosopher | I think profit maximization is a powerful way to introduce (or at least run applied word problems) maximization problems Something like adding salespeople to a territory (more sales, but declining benefit/person added because of competition) versus cost (say linear per salesman). Money is important. Unfortunately, most of the examples on YouTube are kind of clunky. | |

The upper-semicircle has a relative [well, absolute...] max at $x = 0$; so the tangent line there has slope $0$. The radius associated to this point aims due north, so they form a right angle. For any other point on the circle, draw in the relevant constructions and rotate to the aforementioned scenario; the angle between radius and tangent line doesn't change, and so it's right (as desired). | |
