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…

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 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. …

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…

So, I wanted to do my IA on optimization, and so I immediately thought of a soda can, but that is too simple. How can I make this more complex? By maybe optimizing a coke bottle so it's not just optimizing a cylinder? Please help me, and if I were to do this, I'm not sure how... like somehow graphing that and then finding the area under the curve using integration? I'm really not sure

Hi all, I was wondering what you guys do for taking notes in math. Currently, I have a notebook where I take down lesson notes and then after class, I draw a line under and do practice questions from the textbook. I feel like this isnt the best organisation because my the working out for the textbook questions is really messy and that gets mixed up with the important notes. Any suggestions? Thanks!

I am starting the IB in september and will be doing the Maths HL course. I have seen how one individual doing the Maths HL course struggled to find a topic. I would like to use the summer break to begin researching as I do not want to have to do most of the research later on as I know i will have other work to complete. 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%. I need math aa hl for uni req and acted all high and mighty with my parents saying I like math(I do actually like calculus) but I have a parent teacher conference …

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 …

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 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.

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 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!!!

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,…
