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…

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 …

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'm doing a math IA on blackjack, and i have redone the probability chart that tells players what they should do in each move based on my probability calculations. 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...…

I want to do my IA on calculus or differential equations but any idea i have (e.g. Game theory, SIR modelling) is too simple for AA HL and i want to score full on exploration. I did consider Riemann Hypothesis but it seems like differential equations score well, and I'm a mediocre HL student. Anything about differential equations that lies within the scope of math AA HL?

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!!!

But then I don't seem finding anything involving super cars and calculus. I wanted to do something with launch control in a car and how could it help a car at the start of a race to avoid burnout but don't know if there is calculus? I also wanted to talk about Bernoulli's principle and how a wing could help drag but again do not know if the calculus involved is sufficient?

Im a hl maths student and i wanted to do my maths IA on a topic related to calculus as that was the option that my school choosed. And i came across optimisation of packagings. However ive seen that many people simply use the differentiation method to find the optimum surface area of the cans or products they are investigating. Hence to make it more complex i would want to use a unconventional theory or equation such as the brachistrone theory to find the optimum surface area of a can. Is it possible are there any other theories that i can use? and should i find the optimisation of a can or are there other things that i can find the optimisation of? or is this too simple,…

I have to have my IA topic picked out as soon as possible, and one topic that I came up with was finding the relationship between the height of a hyperbolic paraboloid (as a roof) and the weight it can withstand. I will personally engage in this topic by 3d printing different heights and testing them out myself. I was wonder what HL math could be used in this topic, what I have so far is functions (partial derivatives: used in the background information in stress formulas to explain why the hyperbolic paraboloid is a good roof), statistical tests (to find relationships). Any help whatsoever would be appreciated.

So far for my math IA, I've come up with the following: I will research individual countries' economic and weather conditions. Using personally made formulas to calculate a weather score and economic score for the countries, I will pinpoint which roof is best for that country, then I will test out the top few picks by 3d printing them and testing them with weights and etc, and find the best overall roof. Basically I have no idea how I'll do this and I don't know the HL math that will be used in this process, and I'm wondering if I'm over-complicating it.

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 sure whether my approach is correct. Any advices will be appreciated. Cheers…

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?

I have a question concerning criterion D, reflection. So, in the N14 subject report they state that "reflection needs to take place throughout the exploration, through candidates isolating themselves from the problem, to see it from another point of view and to analyze its limits...", now what do they mean when they say that we should analyze the limits of the problem? I get that we should reflect and evaluate our approach and recognize limits such as assumptions but what’s this all about?
