  1. So basically, you don't really need to do much experimental research for an EE in mathematics unless you have a specific topic that can be tested in real life with experiments such as modeling the curvature of chains. You will probably only need theoretical research and to make sure to cite the sources you use. Also the word requirement is kind of different, my word count was only 3366 for example and I got an A. I had a lot of diagrams and equations however, those are the important parts. Personally I'm not that good with probability / statistics but it seems like a good topic. Your
  2. hmm... it's been a while since I did this but I think you want to do something along the lines of this. To figure out if the correlation is significant or if it is due to randomness you can use the null hypothesis. The null hypothesis works something like this. You assume your data does not show significant correlation. Significance in this case means that the correlation is meaningful and not random. You then have an alternative hypothesis, which in this case is that there is a correlation between the use of snuff and oral cavity cancer. By finding the p-value from your data, you can de
  3. Yeah, I would have personally chosen calculus given the choice but my school only offered discrete math. It was interesting, and it did help me understand math in a new light. However, I would not recommend taking it because it's pretty difficult since most prior knowledge of mathematics gets thrown out the window. For your IA, I'd say just start by thinking about things that interest you and that might be related to math in some way. Alternatively, if you actually have a genuine question you're curious about you could research that topic.
  4. date someone in IB and pass it off as "service". serious answer: try to focus on school but if there is someone you like go for it but make sure they understand you can't always spend time with them everyday
  5. I got my physics teacher a bar of chocolate and a card with some physics jokes xD If you're feeling ambitious you could try making a simple LED circuit with oscillating lights or maybe a circuit that plays a little tune. A mug with a physics joke would probably be easier though. The best thing would probably be something personal and unique. For example I used to always ask very specific nit-picky questions to which my teacher would tell me to "shut up and calculate". I wish I could have found a mug with that text on it
  6. 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 thoug
  7. Sure, I can't post my Math IA here but if you message me with your e-mail address I can send you a copy there.
  8. Sure! If you don't mind, can you send me a private message with your e-mail address so I can send you a copy?
  9. Sure, if you send me a message including your e-mail I can send you a copy of my math IA and answer any questions you may have.
  10. By the way, I found my Math IA about celestial navigation so if anyone wants to read it just send me a message with an e-mail or some other preferred method of file transfer and I'll send a copy. In case anyone was wondering, the elegantly worded IB-style title is: Mathematics Exploration – How can celestial navigation be mathematically modeled to find one’s location on Earth when time and the position of celestial bodies are known?
  11. Hey, sorry for the slow reply, I've been busy and almost forgot to reply. I don't actually know what I got on my Math IA but on my EE in math I got an A.
  12. I'd love to tell you more about the topic and my IA and I could even send a copy of it if the IBO and your school both allow it. If you want specific help with the topic feel free to message me and I can even provide some quick online tutoring on the topic if you would like. I'm going to look for my Math IA, I know I have it saved somewhere but it's been a couple of years so I don't remember everything. Here's what I remember. Basically the way navigation works is you have 3 celestial objects, usually stars or in the case of GPS, satellites, and you are able to measure angles and find you
  13. Thanks for the advice! Well, at my school we're using the Haese books and the book mentions about 70 theorems/corollaries and their proofs. I'm not entirely sure which ones I'm expected to know. I'm pretty good with modular arithmetic so I'm not too worried about that. However, while doing a past paper 3 I stumbled upon a question asking me to prove that GCD(m,n) * LCM(m,n) = mn. I think I would be able to figure this one out on my own but I'm worried about the time limit. Usually with proofs I end up taking different approaches and then scrapping them and starting over and I feel li
  14. How about proving that certain numbers such as the square root of 2, square root of 3, π, e and ln2 are irrational?
