Hi all! I'm currently using the "Mathematics for International Student" (Haese & Harris Publications) as my main maths textbook and I was wondering if that would be enough for me to achieve good marks for Maths HL. There's another Maths book by IBID press but I'm not sure if its worth for me to get it Or should I just do questions from past papers? What ar ur thoughts?

Author's Note This is the third draft of a concise guide I'm working on in regards to the new mathematical exploration IA; this started as an HL guide but has now been generalized to include the SL curriculum as well. Please do let me know if there are any improvements you can suggest, or any questions you have after reading through this. I plan to keep this updated and add to it as I work though my own IA. Thanks for taking the time to read through!

I'd love it if you could share some tips and tricks for papers 1, 2 and 3. I'm at a stage where maths is kinda worrying me. I'm on my holiday break right now, but when I get back to school, my teacher's getting us to do all the papers to 'give us a chance to get higher predicted grades' for our uni applications. He's also said that if we don't manage to get at least a 4/5 overall, he'll enter us for the standard level maths paper which I really, really, really don't want and can't afford at all. As the dreaded may exams are inching closer (four months to go!), the worry's slowly consuming me. So, I thought about perhaps starting a thread where we could somehow gather…

I have been reading into the IB programme and the subjects that my school has assigned to me for the next two years, and the one that worries me mostly is Maths HL. I am a good maths student but whilst speaking to other people and reading this forum I have gotten the impression that the subject is quite difficult and challenging, but also I have some questions. 1) Discreet mathematics; series and differential equations; sets, relations and groups; statistics and probability. Shall my Maths HL class encompass all of those or only one or a few? Are they all needed to pass the IB Maths HL exam? 2) Considering the difficulty of the subject, should I make an effort during this…

Hey, Currently I am thinking of doing Dijkstra Algorithm for my IA (calculate the shortest distance), but it doesn't seem enough, what should I do?
Last reply by eylul, 
I am currently thinking about Math IA on the topic of graph theory, but I don't know what to choose from there. I would like to do Dijkstra's algorithm and would like to know whether it would be complex enough for HL. I am thinking about the question of geographical traversal and finding the shortest path from London to Moscow using roads and cruises to cross the sea.

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 thought I would make a post offering to share some of my resources and advice based o…

I decided to take math HL for next year (grade 11). But everyone keeps scaring me about it. All my future iB friends have all taken English HL. They all keep telling me about how math HL is like suicide. Like how these kids who took regular math had like 98%, they came into math HL and ended up with 60%. I don't want my mark to be 60%! To give some of my background, I am NOT a genius, but I do enjoy math a lot. For those of you that know the Cayley math conest, I got 114 points, putting me in the top 15% of kids my age with math. I enjoy math class currently, becaues I am in regular classes, and it is so easy. I have always been in "regular" math, and never had to work ha…

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?

Heya, so basically for my math IA I decided to make my own life hard and choose a topic like 'celestial navigation'. More specifically, I'm doing my paper on smthing along the lines of 'how to find your geographic location using celestial navigation'. Soo, I was wondering if anyone could possibly help me out? I've found some resources but I'm still very confused on how to use them and stuff like that, so if anyone would be willing to lend me a hand, pls let me know as soon as you can, bc ya boi is running out of time due to my own procrastination.

Hey guys, I was woking on my maths internal assesment when I decided to look up soome examples online about my topic (golden ratio on my local city) and I found out that the topis is "overused" and that I could get a bad grade because the topic lacks from creativity. This golden ratio in architecture topic really interested me and even more considering that theres no information about it being used on my city online (Im from Montevideo, Uruguay) so I would be the one that makes the whole progress and maybe, that could compensate tge creativity issue. What do you guys think? Is it really like that? I also have concerns on the mathematical usage as I havent found any cal…

Dear all, For my maths IA I have derived my own mathematical proof of Rothe's formulas for the generation of involution numbers. I did not seem to find any such proofs online, I only found the formulas themselves; I came up with a method for both the summation formula and the recurrence relation, however I am also planning on extending this to applications in group theory and coming up with the exponential generating function. Does anyone know if I would be able to publish this in some small journal? I got the green light in terms of copyright. Thank you!

I was planning on doing my Math AA HL IA on the collatz conjecture and try to predict it. Im using coding to create an experiment sample for Personal Engagement and then create two equations a polynomial equation to predict the sequence and test how accurate it is. The other one is using logs or mod im not really sure and again I test its accuracy. I just wanted to know how good this is or if its too basic because im not sure if this is even right and what else I could add.

Hi guys, I was having a lot of trouble picking a topic for my IA, because from what I know we have to pick a topic that goes beyond the syllabus? So my teacher suggested the topic of Safe and Effective Medication Dosage (Calculus Modelling). It's great because she'll definitely like it, but would the IB? I've been able to find a lot of papers on the topic  she got it from a different program's Calculus book so, yeah, it's fairly wellknown  so I don't know if that would make it less impressive. I'm also not sure whether the topic would let me go indepth enough. It seems simple if I take it just on a basis of dosages, time between them, and time for medicine …

Hi Im horribly stuck on my math ia. I procrastinated a lot and now only have a week to send in my first draft. I can’t choose a topic. I saw the topic finding the length of a curved road which seems fairly simple. I might have to go with it but im not sure if it is enough for math hl. Other than this I thought of fractals but seemed too theoretical, I want to have a specific real life situation to work on. Does anyone have ideas? All help appreciated, I really need it.

Hello, My teacher has just recently told me and my class about the Math IA. I'm wondering if these following two topics I have come up with would be viable for a possible Math IA, or if I should change course and choose a different topic: Correlation IA on the number of human cannibalism cases (from 1900s to present day) and the presence of environmental stressors (environmental stressors are defined as events or things in the surrounding environment that cause stress; for example, lack of food and clean water, physical and mental ailments, etc.) Logarithmic IA on the number of rats and the spread of plague/number of disease cases.

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!!

Hii My IA idea submission is due tomorrow and I have no idea what I really want to do, but came up with the idea of optimization using differential equations. I thought of reducing the surface area of packaging in different shapes like sphere and prisms, and calculate the minimum point (minima) through second order differentiation equation. I am also planning to then apply this to different real life examples like Toblerone triangle prism or something like that. Do you think this is too simple at the level of maths HL because it is just at the level of maths HL in the syllabus? I am ready to discard the idea if the maths involved is too easy for HL. Thanks xx

I've gotten to the stage where I need to write my IA in Maths AA HL. When it came to brainstorming I had an idea that I ended up pursuing in my Extended Essay (pathfinding algorithms) so I was left with nothing for the IA. I started researching pseudorandomness and a mathematical approach to it but it seems to me I bit off more than I can chew. There are ideas of recursions, sums and normal numbers but I don't really see how I could apply it to this format. For example, there is a function which was proved as a way to generate normal numbers which can, in turn, be used to randomly generate numbers but would I have to prove it myself in the paper? H…
