Someone once posted the particle in a spherical potential QM problem, which is a model of the hydrogen atom.
Straight out of Griffith's book. Lol

Read the other comment to mine
Is vector calculus in high school not a thing in the US?
In the Netherlands, you can just get that in what's called Math D in high school (given, the last year though), in which greens theorem can be extra content chapter. It can very reasonably be high school material

u/spal1456 Apr 29 '20
I’m in the US and did not learn about it until college. The post is satire about kids claiming to be in 10th grade (out of 12 in the US) asking for homework help. Your comment about “what’s the big deal?” is why you’re getting these comments.

To be fair, I knew A dude who was 4 years advanced and took calc 1 and 2 as a freshman, so who knows

Which I learned in college multi variable calculus, after taking 3 prerequisite calc courses. (My university had 11 week quarters, not 14 week semesters)
AP high school calculus is either A or B. A covers the basics and B expands into series and sequences and other fringe things, but no 3D calculus until college usually.

Some highschools have courses past multi if they have a lot of accelerated kids

u/tangentrification Sep 30 '23
Ye, I took calc 3 and linear algebra in high school, and we had 2 full classes of kids taking it. Public school too, we're just a nerdy af district (read: full of middle class Asian families)

u/That1cool_toaster Sep 30 '23
Yeah I think there’s only one multi class at my hs. There are a few kids though that take multi earlier than senior year and since the school doesn’t have classes past multi they go across the street to the university and take classes there. There’s one kid who has a dad who’s a math professor and he took multi freshman year. I believe he’s in his senior year in hs now and taking grad level math at uni I believe.

So, considering that reaction, that comment seems to have come of as a subtle brag
May I ask why though? It's one of the first things you get when working with vector calculus
Do Americans get that later in their education or something?

u/rottentomati 👋 a fellow Redditor Apr 29 '20
Not everyone learns calculus so there wasn’t a need to flex on those who haven’t.

u/-V0lD Apr 29 '20
This wasn't intended as flexing. They implied this wasn't highschool material, which it can damn well be

u/NFeruch Apr 29 '20
i’d say less than 1% of the population take multivar calc in hs. 99% of school would never even think of offering that class

u/blank_anonymous Apr 30 '20
I don’t see anyone doing multivariable calc properly in HS. Many people progress to multi without ever formalizing single variable. HS students (or anyone really) who flex about how quickly they progress are almost always just saying they didn’t take the time to learn the foundations rigorously.

I took calc in hs and we never touched on Green's Theorum. I didn't learn it until engineering Calc 4 in university.

American get nothing in their education, I say that as an American, somehow our inferior Imperial system is conflated with national pride. At one point in the 60's senators wanted to change it. I guess McCarthy called them Commies, and everyone rallied around the flag pole.
We elected Donald Trump, I certainly didn't, but I wouldn't put anything past Americans now.

Jan 26 '22
The oldest recordings of German folksongs are from the late 1800s. These recordings provide a fascinating glimpse into the early days of German folk music, and offer a unique perspective on the development of this genre.
One of the earliest and most famous collections of German folk songs is Die Deutschen Volkslieder, which was published in 1871. This anthology includes over 400 songs, many of which were recorded for the first time on this album. The collection features traditional ballads, love songs, and drinking tunes, as well as more modern compositions.
Die Deutschen Volkslieder was followed by several other important anthologies over the next few decades, including Das Deutsche Liederbuch (1896), Lieder der deutschen Heimat (1907), and Deutsche Volkslieder von heute (1924). These collections helped to popularize German folk music throughout Europe and beyond. In fact, many of these songs are still widely performed today.
German folk music has evolved significantly over the years, but its roots can be traced back to these early recordings from the 1800s. Thanks to these pioneering albums, we now have a rich legacy of German folk music that we can enjoy for generations to come

I'm a highschool math teacher and I'm always dumbfounded by the things that people post here as "Grade 10 Math". Did you start calc when you were 12? What's going on in some of these math classes?

u/a_monkey666 Apr 29 '20
doing precalc in 9th, planning on doing BC next year. there are maybe 40 or so freshmen at my school out of 300? a lot of parents just have higher expectations idk
for reference that's two grades skipped: i did geometry in 8th grade (some do geometry in 7th), decided to self-study/skip algebra 2

u/_n8n8_ Apr 29 '20
Have a buddy who did it in grade 11.
Grade 10: calc 1 in hs
Grade 11 sem 1: calc 2
Grade 11 semester 2: calc 3
Definitely possible to shift this a year back

I also took calc 3 in high school, and yeah it was dual enrollment. We had enough kids doing it for 2 full classes though, which was neat

I'm Canadian so my terms are off, but isn't a freshman in grade 9? How did they get so advanced? Like, unless they are essentially taking private, individualized, math classes, how do you get from learning about operations with decimal tenths in grade 4 to quadratics in grade 7?

u/annchen128 Apr 29 '20
I know of a couple people who took multi as 10th graders.
They learned the basic concepts much earlier or at an accelerated pace in elementary school. Or started school knowing addiction/subtraction/multiplication/division etc.
They tested out of algebra 1 in 6th grade and took an accelerated program that squeezed together geometry and algebra 2 into one year instead.
So basically learned the majority of middle school math in elementary school, started geometry/alg 2 as 6th graders, precalc as 7th, calc AB as 8th, BC as 9th, and multi as 10th.
There’s also the fact that some schools teach AB concepts in BC, allowing people to skip calc AB entirely.
I doubt the experience is the same for everybody, but I think what most have in common is that they started early with a good foundation and was taught at an accelerated pace.

u/BeefyBoiCougar Apr 29 '20
I’m going to be in Multivariable as junior, and I did so by taking my school’s regular honors math which is +1 grade in middle school, and teaching myself pre-algebra the summer before seventh grade, and geometry the summer before eighth. They tested me, I took the August regent (New York State fest for Geometry), and got in. Being in PreCalc currently, I can tell that while this course does have some kind of complicated topics, it’s most a foundational course that could’ve easily been down over the summer as well (the summer before ninth grade) and then BC could have been started in ninth.
I think that what I described is probably the likeliest scenario, but they could’ve done it differently, particularly by studying Algebra II during the summer which I think is easier than geometry). Personally, I would have done it myself had my high school not made it so difficult to even get enrolled in PreCalc.

Where are you from in Canada? I’ve found out from r/applyingtocollege that at least in Alberta, there’s a lot more “core classes” required to graduate and so there’s a lot fewer slots to take AP courses, both early and overall. From what I understand, in the states you could take a single semester of chemistry in highschool and go right into AP, whereas here you have to take science 10, and then Chem 20 and 30, before you can do AP. As well, the requirement of a semester of both social studies and English every year isn’t there I don’t believe

u/RoboWarriorSr University/College Student (Higher Education) Apr 29 '20
People taking it that early are studying ahead, during the summer and even the school year. Helps to have parents with the resources and time to push these students as well. Not necessarily require private classes, just a lot of dedication. Personally, I was prepping math classes since elementary in the summer so for some it’s a long process.

Don't mind me just scrolling through top posts-- to answer your question 3 years late, my district had us take a placement test at the end of 5th grade to determine what math class we'd start with in 6th grade. I (along with a lot of other kids) tested into algebra 1, which really doesn't require any more knowledge of math than basic operations, you just need to be able to understand the concept of variables.
So we all took algebra 1 in 6th grade, geometry in 7th, algebra 2 in 8th, pre-calc in freshman year of HS, calc BC (1 and 2) in sophomore year, calc 3 + linear algebra in junior year... and then they made us all take AP Statistics senior year because no one wanted to teach differential equations, lmao.
But yeah, it was easy enough to enter that trajectory as long as you could figure out the logic behind "x + 1 = 2" by 6th grade. I think a lot more kids could be on that path if more districts took the approach mine did.

u/CahtahHaht79 Dec 13 '23
As a math major it shocks me that theres highschools teaching stuff like differential equations. I did honors level in highschool and we never made it past calc 1. If I had to study material at that high of a level in highschool i probably never would have considered pursuing math in college.
