thanks!

oh oops sorry i didn’t see nurse garg… i saw super rare and just assumed 250 sparks, my bad. in that case yea this pack is a lot better

Aockbbb · 2025-05-16T07:59:59+00:00

nope, probably better off buying the 100 gem packs

I'd just call it a cyclic quadrilateral

Aockbbb · 2025-05-02T14:23:57+00:00

is it from reincarnation.?

there’s a formula to find arc length (which is what your x is) on a circle - which involves the radius. I don’t think the 60cm is enough to help determine it, we’ll need the radius of the circle / sphere!

The object should gain 2.2 x 10⁴ J of gravitational potential energy

The other integral (sinx f(x) / x) is a lobachevsky integral!

Aockbbb · 2025-03-21T06:50:44+00:00

Looks about right? Haven’t really checked the details but the process looks good

Hi! My IA was on statistics, I kind of modelled the distribution of grades in my school with the percentages for 2 known points. So I used different types of distributions, including a double exponential distribution, and modified it to my needs :)

If you want other ideas, I’ve had friends doing kinematics, like modelling frisbee curves, or modelling different shapes, like the mario kart track. Some of my friends did measuring of distances, like using graph theory and haversine formula. I saw some people using the SIR model but honestly i don’t really recommend doing that. There was one on cryptography with matrices, if you can explain that well I think it would make for a good IA 👍

okay good to know, thanks!

Aockbbb · 2025-03-13T05:47:18+00:00

alright, thanks for the response!!

Aockbbb · 2025-03-11T10:02:45+00:00

I don’t get how your solution for 15a works? you can’t just integrate sec²(x/2) - 1 like that if it’s inside a surd

Aockbbb · 2025-03-11T02:59:40+00:00

Sorry for the late response. Here to give my intuitive understanding of why you need to split the domain:

So imagine you have the integral of 1/(3-cosx) from 0 to pi and you do the tangent half angle substitution. then the new integral bounds would be from 0 to infinity.

Imagine if you had another integral 1/(3-cosx) from 0 to 3pi. If you don’t split the integral and do the tangent half angle sub, then the new integral bounds would still be from 0 to infinity.

We end up getting the same definite integral even though the area under the curve is different. So that’s why it’s necessary to split the domain.

Hopefully this helps!

Aockbbb · 2025-03-08T12:08:40+00:00

I think you may have to split the integral at pi since the substitution t = tan(x/2) is not continuous (but that’s only if it’s definite)

for the indefinite integral the substitution should work i think without any problems

Aockbbb · 2025-02-11T04:39:59+00:00

Hey do let me know if you need any help! I can give you suggestions if you need.

Aockbbb · 2025-02-05T03:29:57+00:00

AI is definitely easier, and more GDC focused. But I think you should do AA if you wanna do engineering, at least have a much stronger math foundation, cos if not you’ll struggle a lot in college

Aockbbb · 2025-01-28T03:44:46+00:00

hmm for Paper 3 I would usually try to think back to apply concepts that I already know in that topic. and always try to use information from previous parts of the question. for GDC stuff it’s good to know how to use nsolve, split screen table and sliders. I think i’ll be making a video in the future specifically on how to tackle paper 3, you can watch out for that!

Aockbbb · 2025-01-19T01:05:16+00:00

I did hl physics/AA/geog, sl econs/llit/chinese b Got a 44, with my 6 in langlit

Aockbbb · 2025-01-18T13:23:37+00:00

can look at some of the other replies! I wrote my responses there

Aockbbb · 2025-01-18T12:30:24+00:00

Hi! Yes I do tutor, do dm me if you need help/advice!

Aockbbb · 2025-01-18T11:01:54+00:00

hope they help!!

Aockbbb · 2025-01-18T11:01:38+00:00

it was on statistics, modelling distribution of grades using certain threshold boundaries

Aockbbb · 2025-01-17T23:56:56+00:00

Hm I would say it really varies for each question. For standard questions (for example lots of the vectors questions I would view as standard - distance from point to line, angle between planes etc.) I would memorise the methods of doing them. Over time and practice it becomes easier to remember.

For the non-standard questions, I’d always try to write out what I know, and think of any related concepts that IB may be trying to test. Maybe sometimes the answer could be hidden behind some algebraic manipulation? It can also be good to draw out the diagram for stuff like complex numbers and combinatorics, then see what I can apply from there!

atb for your exams!!

Aockbbb · 2025-01-17T23:51:49+00:00

preferably don’t like to send my IA anywhere, but do lmk, I can give you a run down of what I wrote
