Hi guys, I'm about to submit my IA idea for math and I just want a few pieces of advice choosing one. Currently, I'm very much interested in cryptography and machine learning which are the topics that I want to do my Math IA on, are these viable ideas? Earlier when I talked to my teacher, he said that writing about the Global Positioning System (GPS) would be a great idea, but I'd much prefer the other two topics. What should I do to ensure that I get a high grade while doing something that I actually enjoy?

I graduated IB in 2018 and studied Math HL with discrete math as my option. I also wrote my EE in mathematics / physics and received an A. I'm currently studying programming / computer science and game design. I replied to a post a few years ago about writing Math IAs where I gave some advice and talked about my paper and a lot of people requested copies of my IA for reference. I've heard that with the covid situation and online learning a lot of people are facing some challenges with their research and are doing explorations based on previous students' work etc. With that in mind I thoug

So I'm currently working on my IA project and I'm debating between using statistics and probability (AI and AA), calculus (AA), or a mix of both. If you're wondering, last year I had AI math and this year the class did a majority vote for AA (yes I know it's super weird but with covid, AI and AA classes were mixed together and they're pretty similar according to my teacher so). Anyway, my topic is how a cure for Alzheimer's disease would affect mortality rates in the U.S. and what that would that look like on a graph (or whatever math visual). I'm using HIV/AIDs as a reference since dementia c

Hello! I want to do my Math IA on modeling infectious diseases, but I'm pretty sure that would involve using computer software (modeling programs) to solve the equations. Is that okay, or can I only do an IA on differential equations that I can solve by hand? Thanks in advance

I am am work on my mathematics extended essay, and I want to do it on: 1. Coming up with a general formula for the volume of the five Platonic Solids (I need to know from other mathematics higher level students if this is two simple). 2. The proof(s) for Euler's polyhedron formula. 3. The Travelling Salesman Problem (not sure how much math is involved as opposed to computer science). I am most interested in the first but willing to drop it if it is too simple. I am also open to suggestions of other interesting topics in geometry (the subject I have the most interest in).

So my math teacher asked me to submit an IA topic by the summer break for the Math HL exploration. One topic I was particularly interested in was the hedonic pricing method, which is statistical regression technique that is used to estimate the market value of real estate properties such as houses etc. However, I'm not entirely sure if such a topic would be feasible as I'm worried that my IA may turn out to be more economics based than math based. Any advice would be much appreciated.

Hey guys, I made a post earlier and I did not get any replies. I am really desperate this time. Does anyone know or know somebody who will be able to give me some help on benford's law for my IA. I need to be able to understand the depth of it to write my IA and any help is appreciated. PLEASE ANYONE WHO KNOWS ABOUT IT, REPLY PLEASSSSEEEE Usually it is a topic taught in univeristy classes and commonly in economics! THANK YOU EVERYONE FOR HELPING ME OUT (if anyone does....PLEASEEEE..)

So, as I further dive into post-graduate papers I simply do not contain the brain capacity (yet?) to comprehend, I'm gaining an increasingly certain belief that doing an HL exploration on chaos theory/it's applications is not my cup of tea. (again, yet(?)) Our option topic is calculus, and what I've come to understand (with questionable accuracy) is that the chaos theory falls rather into the "discrete maths territory", whatever that is. I've already suggested the topic to my teacher and he appeared to have no hesitations on asking for the rationale and the mathematical development, due yester

The school I'm going to right now is pretty new, our class is going to be the first graduates for the school. So, a new school means no experience, and you can see that with no Math HL offered to students. Well, they actually do now, but last year when I was in DP 1, they didn't offer Math HL, but then they started when I was my second year DP 2. And I wanted to do Engineering, and the university which I want to go to (Technical University of Denmark) accepts IB students who have Physics HL and Math HL. So you can see the problem, I don't have Math HL because the school can't offer it an

Hello everyone😄 I decided to write math ia about BMI of women in different countries(especially countries which have really different kind of diets). Do you guys think it is appropriate for math HL ia? Also, I do not know which formula I should utilize to analyse topic... Pleaseeee help me😂 Thank you.

Hey! What do the CalTech Admissions people look for in a candidate? How do I maximise my chances of getting in? Any CalTech Alumni here, I would love your advice.

Hey guys I really need some help with my math ia topic. So my idea is to model something basic with resonance using differential equations and then see how closely real life reflects that. Like a child on a swing, wind on waves etc... simple experiments for resonance in springs for example, then do an experiment and compare results to try to understand behaviour. Could be connected to suspension in the bridge. Then try to apply that to the collapse of tacoma bridge if it is feasible. At the moment my teacher said the idea is fine but it seemed to be more of a physics topic? Also I'm not s

I have been trying to think of math HL IA Topic relating to music or guitar, so if you guys have some topic that would like to share, please share! Thank you in advance.

Hello, I am currently self-studying three* subjects for May 2019 as I want to apply for German Universities, for which I needed subjects that my school does not offer. Before registering me with my subjects: Math HL: Option Calculus (self-studied as my school olny offered math studies), Physics HL: Option Engineering Physics (completely self-studied with support from an IB teacher from another school), English B HL (with extra work as my School only offered sl and support from my teacher), History HL, Environmental Systems and Societies SL and Spanish A: Literature SL, I sent a mai

Hi guys. I'm in my last year of Math IB (SL) and I'm in desperate need of some guidance. I have no idea how to go about doing my IA. I've decided that I want to find the optimal speed at which a vehicle (a tank specifically) should travel to get the best fuel efficiency. Along with this, I might also try and figure out the temperatures at which oil would freeze inside the engine by like graphing/modelling it somehow?????? As you can see, I'm really lost and I don't know how to approach this topic and I don't even know what math I should be using. Any advice on how I shou

Hi I'm wondering if anybody can explain the reverse chain rule to me? I don't mean the whole U-Substitution thing, I mean the "shortcut" way. The formula is ∫f'(g(x)) · g'(x) dx = f(g(x)) + c. Also, we haven't learned calculus and trig or calculus and logs yet so please just use basic equations in any examples. Thank you!!!!

Hey guys, I'm in a pretty stressful situation as I can't decide whether to change my current SL Math to HL Math, and we're already getting to the point where it is too late to change. My situation: Currently taking HL Bio, Chem, Eng A Lang/Lit, Danish B and SL Math, and History. I want to study medicine in the UK after I graduate in 2020, and my dream is to go to Cambridge, but as I've read on their website only 2% of acceptances go to those who only have 2 subjects out of HL Bio, Chem, Phys, and Math. As I can only have two sciences, my only option is to switch to HL math (whic

Hello everyone, I need Math HL IA ideas, which are not overused! thanks in advance!

Hey guys, Im not sure whether or not IB goes into Permutations and Combinations too deeply or even at all. I've asked my seniors and other IB schools if they did this topic, for which i got a reply saying no. IB HAS stated Permutations and Combinations in their 2016 syllabus so does that mean it's going to be in IB diploma exam? btw i start the IB program in 2 days

Hello Everyone, I am a graduate of the IB on MAY 2018, and I had always been a student who was pretty good at math. I did MYP, and slid through it with 7s all along in Math. I then was told by my teacher that Math HL would be suitable for me and that it would be a good challenge. At that time I thought, yeahh but I will just go in and prove that its easy. My first Sequence and series test, I got a 3, and was in terrible shock, I had never seen below a 7 in years in Math, and the MATH HL IB CLASS had a first test given to me that was a 3. I continued and it seemed like after I had a talk w

I’m a little conflicted about choosing which subjects to take as higher levels. My school forces us to take English and History HL, so I basically only get the option of one other HL. That will probably be Chem, but I’m also considering Math HL. Because of my school’s requirements I’ve been considering taking 4 HLs since I hesr that colleges don’t often look at SL classes. I’m a straight A student, but I struggle with time management a lot, and I realize the commitment I’d need to make. Not sure if I’m making any sense here, I’d just appreciate some advice on deciding, maybe some perspective f

Geometrical designs used by architects in different places of the world. Math is a tool through which beauty can be calculated using ratios and therefore architects use geometry and many other mathematical concepts to build buildings. Some concepts to explore are geometric proofs, constructions, the Golden Ratio, and the Fibonacci Series.

Hey guys, I was sick and missed some math classes. Here are two questions that I can partially solve them but not for the second part. It would be great if some of you could help me with the steps and process. For this question, I got that when x=0.4, y=1.573, but I don't know how to justify whether the approximation if greater or smaller than the actual value. For this question, I found that the Maclaurin series is ln(2) +1/2x+1/8x^2. I wonder how could we use this to solve part b.

Hi friends, Following up from my previous post, I talked to my math teacher as I found an egg shape building, and what I'm planning to do is model the building by volume revolution from a curve, and then maximise the space inside. However, I don't really see the HL part of this and it seems like something SL could do as well. Any ideas on what kind of math I can include to make it more suited for HL? Thanks for your input!

Hey, so I really need to get started on my mah IA, and I'm really interested in the area of architecture. However, I'm really unsure and have gone to my teacher a few times but i still feel really lost. Basically, I have some unique shaped buildings, my teacher suggests that I try and maximise the space within this particular round building. Does this sound too simple for HL math? Initially, I had a twisted building and I was going to calculate the volume loss, but I have no clue how thats going to work. My teacher had said it would be a good idea but then she asked me to do the other bu
