Ok yeah whatever Aoyama might be the traitor. I don’t care right now. (Even though it’s super fucking tense and holy crap I love this manga)
What I really care about is this part of the chapter.
This is some advanced calculus right here. I can’t quite make out the equation entirely, but it looks like the following:
It’s probably not exactly the equation since the print is so blurry, but I can definitely make out a familiar looking equation or two.
For those of you who’ve taken Calculus, it looks like a weird (and difficult) integral. But more so than that, these are very special equations in mathematics that are almost never seen in high schools in America: The hyperbolic sine and hyperbolic cosine functions.
While normal sine and cosine have to do with the vertical and horizontal displacement of a point on the unit circle, hyperbolic sine and cosine (sinh and cosh) do the same thing except for the hyperbola.
Needless to say, as a guy that loves math I felt like this was really advanced stuff for a bunch of second year high school students to be learning at the beginning of the school year (since that’s canonically where they’re at it seems).
I did a quick google search to see what the difference between math education in Japan versus America is (because I’m well aware that the U.S. education system is waaaaaaaaaaay behind most of the rest of the world) and I found this.
Apparently Japanese children begin to learn Calculus in the 2nd year of high school and integration in their 3rd.
First off, boy am I jealous, I wish I was able to learn Calculus that early in my education.
Secondly, if you assume that this is the norm for an education in Japan then certainly a highly prestigious school like U.A. might push their kids into advanced classes more quickly than other regular high schools might.
So yeah… I guess it makes sense for these kids to be taking such an advanced level of mathematics even though they’re like… 15
TL;DR: The U.S. needs to teach math better and My Hero Academia is pretty accurate.
