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! ------------------------ Table of Contents Preface and Introduction to the Exploration The Process (to be added) Formatting (to be added) Acceptable Topics (SL) Acceptable Topics (HL) Grading and Evaluation Crit…

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…

I'm beginning to brainstorm ideas for my upcoming math IA and I'm very interested in exploring the topic of music in the context of mathematics. I've played the guitar for nearly 5 years so I would like to focus more on that instrument. I initially wanted to discuss Fourier transform but my teacher advised me not to due to the topic's depth given that this was only an IA and not an EE. I've been thinking of simpler topics I can tackle in that domain but have so far come up fairly empty-handed. Other topics that I've done some mild exploration in have been Pythagoras ratios in guitar frets or beats and overtones. I was hoping to get a bit of advice from anyone that may hav…

I wanted to ask what will happen if I get caught in plagiarism in my math IA? to be very honest, I didn't do the IA by myself and copied a lot of material from the internet. I cited it all though Will the diploma be cancelled? And if it does, the US university which has already enrolled me, will it withdraw the admission? please reply...i think over this a lot these days

My math HL IA was due literally months ago and i dont have anything to submit. At this point I don't expect to pass, I just need something to submit. The final chance to submit literally any document so that I graduate is in 3 hours. I have nothing. No topic outline rubric examples or anything, i don't have any examples or other students because its a 3 person class and our teacher is out. I don't know what to do and if I dont make something up in the next 3 hours I'm not graduating.

Hi, I’ve been thinking about my maths IA and I would like to do it on area optimisation. I would like to relate it to city/urban planning. I was wondering if there was anyway to use inscribed and circumscribed polygons in a circle to show area optimisation and then using L’hospitals rule to prove the proof. How would I relate this to city/ urban planning? And would this work as an IA topic ?

Hey guys, since we are in quarantine and I have no clue what else apart from working out I can do for CAS (and also bc I like maths a lot) I started to make vids about hl math aa topics (in all my tests in math aa hl I got a perfect score or a nearly perfect one so I think I understand them well). I would like you to see the video and give me some suggestions if you have time please . Thanks! This is the link for my first video of some basic problems of complex numbers: https://www.youtube.com/watch?v=g7u_uk5Z5e8

Hi guys, I was wondering if investigating the Fourier Series, and its applications for Noise Cancelling Headphones would be a good and suitable Math HL IA? I'm not sure if it has the appropriate level of complexity, and also if 'investigating' i.e. explaining how this system works in noise cancelling headphones is going to score highly. Should I try and narrow it down, focussing on a particular brand? Also, how can I make it more 'mathematical' as exploring one theorem may not should a great use of maths? Has anyone done any work on the Fourier Theorem or series already and found that there isn't much to explore? If anyone has any comments, tips or advice on this part…

Hello, everyone! I wanted to write Math HL ia about volume of area of an object (for example: torus, bottles, or other complex objects) My concern is whether the topic is too easy for HL IA. Could you please give me some suggestions that can make ia meet the HL expectation criteria? I have really no idea about it... Thank you!!

Hi everybody, I'm starting IBDP this spring and going to take Math HL. I’ve been solving the problems on review sections on the textbooks for Math HL (published by Haese mathematics) recently to prepare for class because I’ve already studied some areas (like quadratic functions and probability and whatnot) at school. I actually thought those problems are not very difficult, so now I’m kinda relieved because I hear many people say Math HL is insane. So here’s my question. Is the final exam much more difficult than them? And Shouldn’t I be relieved yet?

So after reading endless of Ib related threads I came to the conclusion to buy the Haese&Harris Math HL book. But there is this one problem. I can only find a Book from 2008 with the name Haese&Harris. Here a link: https://www.medimops.de/paul-urban-mathematics-for-the-international-students-ib-dipolma-hl-core-taschenbuch-M01876543116.html Is this the one everyone is talking about and is this book good for a 6-7 points reaching student?

Hi, I’m currently choosing my IB courses and I was wondering if T10 US colleges would see HL Math AI as a waste of an HL (our school only lets us take 3 HLs out of 6 IB courses for the diploma program). Would it make more sense to take SL Math AA and another HL. I don’t want to take HL Math AA. I also want to keep my options open for engineering.

Hi everyone, I was wondering if I could get your opinion on whether this topic is appropriate for a Math Exploration in HL. I am planning on analyzing Poker Odds, mainly by focusing on Pot and Card Odds. I will certainly be using conditional probability, Bayes Theorem, Factorials, Permutations, etc. I will basically give an invented scenario and, from there, I will find the probabilities of having a certain hand and of winning based on the opponent calling or betting. I will also use probability to determine if the odds of the hand are profitable to continue playing. So, what do you guys think? Do you think this is a good topic and that the math used is appropriate for H…

I am taking MAA HL syllabus and I'm trying to do a calculus IA on the roller skates and my draft is due in a few days. I am modelling rates of change of roller skate accelerating down a hill, kind of like motion down an inclined plane we learn in Physics. I started off by collecting data of distance and time to generate an equation of motion of the roller skate. That gave me what I assumed is an exponential function because the roller is accelerating down the hill. To further my investigation, I tried differentiation, hoping that it would be complicated. My aim is to suggest a modification to the hill so that I would be able to travel down faster without posing any safe…

Hi, I'm doing an IA on the volume and surface area of a torus, and I've already derived the equations needed. However, these equations and their derivations are widely found across the internet, so do you think it would turn up as plagiarisation? :0 Also, I'm thinking on optimising surface area with a fixed volume, meaning having the largest surface area with the smallest volume. How do you think I can do this, and whether the equations that I have just derived can play a part in this? Thanks a ton

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

Hey everyone! I’m in A&A HL, and this was one of the problems on my homework. I basically had to find the value of theta (in radians) and hence the area of the figure I drew as well. I checked my answer against the one in my textbook (I’m using the blue Haese Mathematics book), but it doesn’t match. Can someone please look over my steps and point out any mistakes I made? Thank you.

Hi guys, I'm doing my modeling maths porfolio on the dice game. You can find the task here. page 4. Currently, i'm doing the last two questions. For the second last task: let say, the player pays $30 for each game, and if he wins he will get his money back and the banks has to pay him as well. So if the probability of him winning the game is 15/36, out of 36 games, he can earn 15x30=$450 and the bank has to pay him a certain amount of money for every game he wins. does that sound alright? For the last task: in the case of multiple players involved in the game, is it that the each player rolls their dice once only or for the same number of times? And how do we decide who w…

Hi all! I am a 11th grader and a Math HL student. I have chosen to model traffic flow using cellular automaton as the topic of my Math EE. However I am not sure how deep can I go and whether my topic is advanced enough to become an EE topic (my school's Math group teachers allowed me to do this topic, but I would like more opinions), because I still have a lot of things to learn about it. What's more, I have looked through some related essays, but I did not find many proves of mathematical theories. Most of them contain mainly words and graphs of cellular automaton, so I am not sure whether my topic contains enough mathematics theories and proves to write a Math EE. …

I would like to do my Maths IA related to Poker or casino games such as the Roulette as it has always been something which I have been fascinated about. But something which allows me to use the required amount of HL Mathematics skills and knowledge. Any Suggestions? I would also like to ask, how is the Maths IA structured what must it contain? …

Can anyone explain the difference between these two formulas? I am thinking of doing my math SL IA topic on time dilation so I need clear understanding on these. I know that one is the time dilation formula derived by using hyperbola and the other one is the famous time dilation formula, but I'm not sure how they are related to or different from each other. (I'm also not too sure how the first formula is derived since I don't have the knowledge from advanced algebra.)

Basically what it says in the title. Context: my school grades on a 1-7 scale similar to ib but more harsh. School focuses on growth( gives predicted based on growth) but I don’t know if I can grow seeing as it just gets harder and harder. I get the concepts and the homework sets I can do. But come quiz come test, the difficulty of the problems seem to be on a different level (gone to teacher multiple times). I got a literal 2 on the test which if I were to state it as a percentage level I got a 12%.

Hey, The rq for my math ia is finding the ideal volume and surface area of lifebuoy ring. By ideal, i meant where a person won't be slipping through it and he/she is able to fit though it. I know that oi need to find the formulas for surface are and volume of a torus. for personal engagement or doing something new, i thought why not find this ideal surface area and volume of lifebuoy ring. Could anyone suggest me how to proceed from here and is this rq enough unique enough for ib not to cut down the marks?

Hi I posted yesterday about my math ia, now I have another idea that im not sure of the math part of. I'm very much in panic mode which is why im jumping from topic to topic without really doing good research first. I'm scared I will spend too much time and find it to be too hard or too simple since I have very limited time. I was wondering if I could do a real life situation regarding optimization. It sounded simple at first but after a tiny bit of research I saw that it can get complex. For example, finding the best route for an airplane to achieve minimal time seemed like a good idea. I think it would include Graph Theory Algorithms as I saw but again im not …

My only issue is a still need to incorporate HL maths in there, and in probability the only thing the IB offers is Bayes theorem. How can I incorporate it in my work? I am open to any suggestion, even a large change in the whole work itself, I just need an angle to look at it where i can use the theorem.

Hello, Unfortunately I found out that the topic I chose to do the math (HL) exploration in, didn't work, therefore I started a new one. It's about the the great pyramid. A lot of historians assume that the built of the great pyramid took only 20 years. I don't really believe that. So actually in my exploration I'm trying to prove that it was possible to build such a masterpiece in 20 years If I'm able to prove that, then it might really taken 20 years. But if my calculations reach 100 years for example, then I would have disproven the assumption. My problem is I want to include difficult math in my exploration, but I don't really know, which topics I may include...…

Hi guys. I am currently considering doing a maths IA that involves logarithmic regression. Whilst I understand that a logarithmic regression line can be worked out by plugging it into a GDC (like the ones my school uses), will we still be awarded for calculating it by hand, using formulae step-by-step, rather than letting the calculator do it all for us?

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.

I have been wondering quite lately when I switched from a petrol car engine to a diesel car engine that it is much more fuel-efficient, I have a math project coming up and I wanted to take this into the further investigation, therefore, do my own measurements and modeling to compare the fuel efficiency in both cars. There will be a rate of change in the mpg when accelerating in the highway but also in the city(in other words there maybe calculus involved?), so is it a good topic to take into investigation? does it have a sufficient amount of math? and if you have some sources about this particular topic please let me know. Thanks a lot!!!
