  1. Guys could you please take a moment to fill out my math IA survey. Here is the link: https://forms.gle/oy8qgy75VRzJA2RTA
  2. Hi there! I am required to submit a math ia topic in these days. I have now come up with an idea to investigate the relationship between Chinese birth control policy and Chinese population. Is it a suitable topic? If it is, what fields do I need to research on ? I really want to get some advices from you, thanks!
  3. CAN ANYONE GUIDE ME UPON THE USE OF DATA IN MONTE CARLO SIMULATION, AND IS THIS A GOOD TOPIC OVERALL PLEASE..I NEED FEEDBACKS
  4. 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?

    Stuck on your Math IA? This is a list of potential topics for your Math IA, approved by my IB Math teacher.
  6. Hi guys, I have been quite frustrated lately with my searches so I came here specifically. I am a pre-IB student in Poland, public school first gen, our first graduates finished IB DP just a year ago or so. Many people at my school are more inclined towards visual arts, history and geography hence why these classes are standard. However I haven't heard of a single person taking HL math and our math teacher said the course is so hard she would only let one person from our class take it. So now we have winter break, I can't really contact her and ask for sure if the class is offered or not and t
  7. URGENT HELP REQUIRED PLEASE I want to do a world studies essay with Computer Science (which I don't study, but will at uni), but I'm stuck. I had planned on crossing it over with economics (one of my standard level subjects) and doing it on the Cambridge Analytica scandal, but my idea doesn't have enough econ in it. I would love it if there are any ideas crossing it over with any of my subjects: Maths HL, Physics HL, Spanish HL, English SL, French SL, Econ SL. I have to get back to my advisor by the end of the week!

    TEXAS INSTRUMENTS 84.docx
  9. hi, im having trouble with question 'c'. i found the position vector of the equation but i cant find its direction vector. anyone has any idea how to do it?
  10. Hello people, so I am writing my math HL ia on the option discrete mathematics. More specifically on graph theory, and the traveling salesman problem. Does anyone know of any useful algorithms I could use in order to find the most efficient route between different points in the map. I just need the algorithm, everything else is ok. Would really appreciate the help, since the one I was going to use seems to have been taken down from the web. Anyways, thanks
  11. Hey there. I am currently in the process of choosing topics and writing a proposal for Math IA. I have chosen a topic on car parking. What I have in mind at the moment is how to park a car perfectly in the parking layout. Well, the use of math that I can see is angles, areas, probability. However, I am afraid that this would be simple as I am taking HL. So, I would really love to hear out your opinion on this topic and maybe some other math relation to this topic. Thank you.
  12. I want to investigate the use of math in GPS. however, I feel like its too broad of a topic how can I make it more specific?
  13. 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
  14. I have 2 weeks to submit my math practice IA. I decided to do something with predicting the stock price but I'm not able to figure how to go about it. I did some research and came across the Monte Carlo simulation. But I'm not sure it there is enough math in it because it just some basic statistics and probability. I then came across the Black Scholes model and it seems like there is enough math in it but I'm stuck on how to go about it. We haven't covered a lot of concepts in class yet so can someone give me some direction as to where to start and what I can do?
  15. What are EE math topics I should avoid? Is writing about RSA cryptosystem or four-colored map too common?
  16. Hey, I don't have a lot of time and I'm desperately searching for my EE topic. I've been thinking about applications of continued fractions or looking for the best way to define pi number by probability. I dunno what to do with the first topic to show my personal engagement and I'm not sure whether the second idea isn't too simple and should be used rather to write an IA. Can you comment on them and/or eventually give some ideas? :/ I feel like committing a suicide but I like this subject... Any tips to survive?
  17. Hi everyone! I need help with my math IA topic. I am choosing between Bayes' Theorem use in real life OR measuring the distance from a star to the Sun (it is just different units, but you have to use simple SOHCAHTOA after). I doubt that it is going to score high because I am in HL and there is not much stuff for Criteria E. Are there any other topics you can recommend?
  18. 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
  19. Hi all, I made a google classroom that is categorized into 6 modules for covering some interesting questions in IB HL. what I'm trying to do is to give you guys questions for each topic, hopefully every day. And I will always attach video solutions for them. Here is the code for you to join: 5btf45 Here is some nice question you can attempt on trigonometry: Question: https://drive.google.com/open?id=1DpdllFl3wkIDNwVDaUSQokN_FC0pUh5t Solution: https://drive.google.com/open?id=13b3TVJYID4KsdUvJRQRNL6KUOoyNiYNS Hopefully you will get some help by the classroom. Any c
  20. Hello! I am a French student doing the IB and I am doing a survey to complete my math studies IA. I would really appreciate it if you could take the time to answer my survey. https://goo.gl/forms/KIMSFSzwaWuudcPz2 Thank you, Thibault
  21. https://docs.google.com/forms/d/1KKZMguXKnIiGoeYc5XJfzZ9285sJzC5HoG6NWV9ocyI/edit HI everyone! I'm currently working on my math studies IA and I would really appreciate it if you guys could answer a couple of questions for the data collection! Thank you!!! (it's in both english and french)
  22. At the end of this year our teacher introduced IA to us and we had to start exploring the topics that we are interested in. As I am planning on pursuing biomedical engineering, I wanted to apply math into our body. Therefore, I liked the idea of math in biorhythms. The plan is I will convert the sine curves of the biorhythms for 3 strands (intellectual, emotional and physical) into co secant curve and then apply integral calculus to find the area under the graphs. But then I dont know if thats enough for HL Math IA requirements. I WOULD BE VERY THNAKFUL IF YOU GUYS COULD HELP ME OUT WITH THIS.
  23. Hi! So I'm doing my internal assessment of finding an optimal route through some points of hte city using the Chinese Postman Theorem. My math teacher says its okay, in fact, he suggested the idea of doing this IA. But I have half of my work now and I think that the math that involves are very easy, so I'm scared that I don't get a good mark because of that. I'm doing the option of calculus, and this is part of the discrete mathemtics, so it's part of the HL syllabus, but do you have any suggestion of how can I do my IA a bit harder? Or do you think it will be enough? Thank you!
  24. Hey! Could somebody tell me how to do the d) part in this question? Why is it LCM 2, 3, 5? How did they get 2, 3 and 5? Thanks in advance!
  25. Hello everyone, I am planning to do my math IA on predictive modelling. I will look at the date from the 100m race in the Olympics from 1896-2004. I will use the logistics curve to determine a function to establish predictive modelling for the Olympics Men's 100m race. I will use my findings to predict the results of 2008, 2012 and 2016, as well as speculating on the 2020 results. Please do suggest any changes I can make or if this topic isn't good enough. Any help would be appreciated!
