need help for the MAI HL IA, deciding topics
freally_struggling posted a topic in Maths HL & Further
hello, right now I'm deciding topics for my internal assessment for math. I'm interested to different online video games and formula 1, but not sure if the topic from these interest can or cannot become a IA topic. The topic i'm looking at currently: - the more eco friendly formula 1 racing schedule this topic would possibly relate to Voronoi diagram and graph theory, to minimize distance travel between different grand prix, but on f1 calendar their are around 22 races; so graph theory might be a disaster. - Genshin impact character damage optimization -
Hey, I am planning on doing my Extended Essay in Math. After doing some revision on my previous choice of topic I came up with a new topic: The geometry of GPS navigation My research question would be: What is the role of mathematics and geometry in particular in GPS navigation? Would that research question be specific enough? Or do you have any ideas for improvement or refining it? My approach would roughly be looking at triangulation, explaining with diagrams how it works and what role it play in GPS navigation. Then I would look at trilateration and how this helps Would including how speed -
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).

I'm looking to write an IB Math HL AA IA (Exploration) related to Probabilistic Language Models (like predicting future words with n-grams) or anything related to linguistics. I'm having trouble picking a topic though that will have the correct mathematical rigor and sophistication and are able to be structured like an IA. Are there any topics within the field that could make a good IA question that I could research? Thank you so much!

I'm having a hard time deciding on a topic for my math IA which I'm supposed to start working on next month. I thought of the golden ratio but I feel like that is a very common topic and would not make my IA stand out. Ive been in the state board upto my sophomore year and this transitioning has been hard as I haven't ever explored practical topics in mathematics. Any ideas for broad topics that I could research on? P.S - I'm interested in subjects like media studies, fashion design, advertising and psychology. Thank you!!

Hello everyone! As a part of my math ia, I am analysing the pharmacokinetic profile of a drug. A part of the pharmacokinetic profile involves finding the area under the curve of the medication's concentration - time graph. I think this area is meant to represent the total exposure of the drug to the paitent's body. This is what it says online as well. In other words, it would be the total amount of drug absorbed by the body. However, I'm not quite sure how this works, as the units used for the y axis (miligrams of the drug in each litre of drug - mg/L) are completely different from the x -
I am really passionate about math and cars, so I decided to do my IA on racing lines and mathematical approximations of them. The trouble is, I am lost as to how to start. I don’t know how to approach this (should I start with a single corner and try to come up with a line for it?), and furthermore, I can’t prove that the line is the best/better; that would be physics. Should I switch topics or could I save this topic, as it really interests me?

This year I'm going to be a freshman and I'm interested in getting the IB Diploma for my choice of mathematics I picked Integrated Math 1, which isn't IB, but Pre Calculous is... I would like to know if I should take Pre Calculous because I want the IB Diploma even though I have no knowledge of Pre Calculous or just stick with Integrated Math 1.

So... I want to do my IA of math aa about the correlation of respiratory diseases and the level of pollution in my country. I don't know if it's a good topic and I want to have a good grade :( Could someone give me more ideas please? I would ask my teacher for help but it is her first year as an IB teacher and my school has just started with the program sooo its kinda messed up Thank you and sorry for my english<3

I have decided to have my Math IA revolve around the probability behind the prisoner's dilemma. I need help deciding on three simple maths and one sophisticated math to explain the game (besides a tree diagram and expected prison sentences). I am afraid that I won't have much numbers/math to work with. Thank you in advance.

Hello everyone, I am currently doing 4 HL's but I need to drop one as soon as possible. Right now I am taking Math, Physics, Chem and Econ HL. I want to be an astrophysicist. I know that I need to keep Physics HL, I do not know about Math because even though I am strong at math, the teachers say that it will be very challenging for me and I will not be able to get the score I want, but if I drop to Math SL she said that the course would be kinda too easy for me not letting me develop my skills. I have to choose between Chem and Econ which one to drop. If I were to have Physi

I am moving to a new IB school in Canada during the middle of ninth grade. In my old school I did Advanced Algebra 2 in 9th grade. Do they have an option of continuing on that path or do I have to start at algebra 1? I also was doing French 2 at that school. Can I countinue that?

Hello guys, as a topic in Math IA, I chose to explore mathematics behind voting systems. According to my research from various papers, its closely related to probability/statistics, but nothing else. If I won't have Calculus and stuff like logarithm in my IA, does it mean it is a weak IA? If anyone has Math sources on voting, please help me out. Thank you in advance

Is finding the derivative of trigonometric/circular functions, like the sine and cosine functions, part of the Math SL syllabus? Is this the level of Math SL or is it more advanced? I'm thinking of doing this in my calculations for my IA. Would it work?

Hi! So my math sl ia is due sometime soon, and I can't seem to get started with it. This is the fifth time I've changed my topic, so I've wasted quite a lot of time. I finally decided to do my math sl ia on this topic: Modelling the development of swimming performance in the Asian Games.I'm planning to focus on the gold medal winning times in the women's 50 and 100 freestyle. However, I'm not sure on what mathematical concepts and processes I'm supposed to use to model it. I've read a lot of literature on it, but I still don't quite grasp the concept of how to model it. I've tried a -
Hi I’m going into math sl and we have to write an IA. I wanted to write an IA on population growth in China but i have no idea how to. Can someone tell me how to write this and if it’s a suitable subject for Math SL IA?

So I am entering my second year as a DP student which is both exciting and unnerving due to the shear amount of work there is to do. That being said my math teacher over the summer wanted us to finalize our math IA topics. I have narrowed it down to two potential topics which are the geometry of ice hockey or how does listening to music affect ones ability to solve math equations. Thanks so much, Maddy

Hi all, I just wanted to know how difficult it's going to be for me to study and succeed in IB. I'm currently studying in grade 10 and I'll most probably start studying according to IB's curriculum next year. I'm currently studying the Holt McDougal Modern Chemistry, English Literature/writing, Biology, and Phyiscs. The McGraw Hill Algebra 2 on top of social studies, Farsi literature/writing and Arabic. I find all of the subjects I'm studying relatively easy (except Farsi. Even though it's my mother language), and I aced all of my finals last term. But I'm kinda stressed to be -
Hello people, I know I will sound crazy/weird, but is it possible to self-study HL mathematics? My school does not teach the HL math, and so I am 'stuck' with SL. I really enjoy maths and I am quite pretty good at it. Also, I want to be a chemical engineer, so HL Chem, Phys, and Math are highly recommended. I am already doing HL Chem and Phys, which is satisfactory for most of the universities, but I really feel like I should also do HL Math. Thank you for your answers

Hello everyone, i am a Math HL student and our teacher is askingus to creat topic proposals for our IAs. Since the level of mathematics used is very important, i want to apply calculus in my ia but i couldnt think of an interesting topic similar to that of modelling rainfall in the sample IAs. So id like to ask for your help and suggest some interesting topics that uses calculus. Thank you!
