I was watching the first episode of Det.Yakumo, and I happened to catch this screen:
A preview of my future, I'm afraid.
We just recently learnt about sinh(x) and cosh(x), we didn’t exactly cover their derivatives yet, but the derivative on the board matches wikipedia. I guess the derivative makes sense, at first I had thought that since it was e^x, the derivative would be the same, but the e^-x probably changes the sign, making the cosh(x) derivative the same as the sinh(x) one. So, I guess the scary part was that I just learnt/am learning this stuff in calculus right now. Anyways, it was an interesting observation, so I felt like making it. I have seen other scenes in anime’s that also had “real” math on the board. I don’t remember which anime, but I think I saw one in which they were doing quadratics in like grade 8 or 9, that somewhat made me realize how difficult school in japan is (we didn’t learn that until grade 10).

I don’t know if I loled or shuddered more when I saw this (haaated maths in school, but was forced to continue studying it for A level, until everyone realised I was failing it and then I took up another Arts subject halfway through the course).
On another note, I really enjoyed the first epi of this, so will defo (well, unless it very swiftly becomes a total trainwreck) be sticking with it.
Good luck with calculus!

Haha, British school terminology. I have been out of the British education system for almost 5 years now, so I haven’t heard much of those funky terms.
The manga only got better, so hopefully the anime will get better as well. I don’t know if my memory is shot or perhaps I didn’t read the whole manga, but I don’t remember their being a central villain like what the anime seems to suggest. Oh well, hopefully the anime will be fun.

Oh dear, I’m still struggling with memorizing all those special angles they make us remember. sin 30, 45, 60, cos 30 and so on. God.
The show looks like great fun though.

Ahh yes, good old special angles. They might seem useless, but you have to use them a lot on tests/exams. Try and memorize them(if you have a good memory), or you can just use the special triangles and figure them out whenever you need them.
I am sure your teachers already told you how to, but just in case here: http://en.wikipedia.org/wiki/Special_right_triangles
Draw those two triangles 45-45-90 and 30-60-90. If you can draw those 2,then there is no need to memorize the angles themselves (and it’s easy, one is a right angled isosceles with a length/height of 1, and the other is Right-angled triangle of side 2.
Oh,sorry for digressing, and yeah the show looks fun.

Calculus is the easiest part of maths – if your maths future is restricted to calculus, you’re very lucky!!!

Sorry for the late response!
Hmmm, I sure hope that what you say is correct. Having said that though, I also have a Discrete Math course coming up soon and a Linear Algebra course as well, so Calculus isn’t my only math,but it does make up a good portion of my studies.

Remember what Madoka had to go through in school?

Oh yeah, I vaguely remember her suffering through some serious math, it probably had some deep meaning like everything else in that show…
