It always gets mez the older I get I better realize how Jank my education was,
Elementary school taught me addition, Middle School Taught me multiplication Junior High Taught me pre-algebra College is teaching me addition, but with common core
One day, maybe for my bachelor's I'll learn some of those funny math symbols.....but not today
I kinda miss doing those relatively simple physics probems like finding how far something goes based on velocity and shit.
I use trig heavily at work.
What's the college one mean?
Stokes' theorem. Almost the same thing as the high school one. It generalizes the fundamental theorem of calculus to arbitrary smooth manifolds. In the case that M is the interval [a, x] and ω is the differential 1-form f(t)dt on M, one has dω = f'(t)dt and ∂M is the oriented tuple {+x, -a}. Integrating f(t)dt over a finite set of oriented points is the same as evaluating at each point and summing, with negatively-oriented points getting a negative sign. Then Stokes' theorem as written says that f(x) - f(a) = integral from a to x of f'(t) dt.
Same as high school but fancier?
It's the most general form of Stokes' theorem that the integral of a differential form over the boundary of an volume and the integral of an differential of this form over that volume are the same. It covers a lot of classic formulas from the fundamental theorem of calculus to Green's theorem, Gauss' theorem and classic Stokes' theorem.
How the hell is "average price" useful?
Thats like buying potatoes and pork chops and saying the average price is $875. Technically true but practically useless.
We did a lot of straight algebra in highschool, I don't need the exact skill but its boosted my abstract thinking a lot which helps in other things
Most of the math I do at work is related to compound interest. Of all the math I believe the general public should understand, the concept of how paying interest to others is a total screw would get my top vote.
I have a co-worker who took out a car loan last week at, wait for it, FIFTY THREE PERCENT INTEREST! No concept of what that was costing her. She could only see, "I can afford the monthly payment."
(1 + r)^n and its friend 1/(1 + r)^n have been the two most important concepts in work and personal life that I've ever learned and applied.
53%?!
Sounds like one of those shitty used car joints “no credit, no problem” that you sign your life away for a mediocre car.
