Hi, I am intending to do my Math Exploration for Math HL on Graph Theory, based on the Chinese Postman Problem. Can you suggest some ideas or areas that I can explore? And also how should I go about doing this Math Exploration, especially being Math HL? Thanks!

I'm currently doing IB Math (SL/HL qualificatory course) and I cannot cope! I did reasonably alright in the pre requisite, with a 94 average- and today I completely failed the first exam with 10%!!! IB Mathematics is hell to me... anyone else feel the same way? For those who don't, how did you achieve success in this subject area? Any advice would be appreciated!!

Hello! Can someone please confirm (or deny) if these two equations are equivalent? I'm unsure about my manipulation of the equation. I'm ultimately trying to obtain something that includes logs. Thanks in advance! --->

This year will be my first year doing IB and I'm trying to choose my subjects. The university I want to get in requires Math HL and I want to study economics. (even if it wasn't required, it's still a good impression to take Math HL.) I have never been a math genius. With studying the night before my math exam, I'd get a score between 70-90 but I would ask A LOT of questions to my tutor... This year, I will study hard and regularly. But everyone on internet says that Math HL is like hell so I'm scared of ruining my life by choosing something I can't do... I like Math when I study, it's just that I don't understand as fast as a math genius... What should I do?

Ok so we had a math ia rough draft due at the end of school, but I had Junior Nationals to go to and train for (5-7:45 a.m, then come back to the pool, (3:15-5:15), for swimming, because college swimming recruiting starts really soon. So I seriously Bs'ed the Math IA rough draft, like crap (I turned it in a while ago). But I have redone the entire thing because it is summer break, am I still allowed to turn it in, or no because it is a important draft? I am so worried, you can message me or anything but if you could anwer that would be great!

Hey everyone. So, for my maths exploration I decided to pick something that I really like, and that is, video games. I found out that vectors play an important role in the making of a video game, so I thought it would be a good idea to try to develop a simple video game by focusing in the use of vectors. My teacher said the topic is alright, but I'm a little scared because I've never heard or read about anyone doing something similar, and maybe that's a good thing I know, but I wanted to know what any of you thought about my topic. Is it good enough for maths SL?

Hi, so I'm going to be taking the IB program in August and my school has given me the option to change my current choices. Currently I have: HL Economics, English Literature, History and Chinese B; SL Maths and Chemistry. I want to become a lawyer in the future, which is why History and English Literature are at HL. But I'm unsure about SL Maths and if I should change it to SL Math Studies because I'm afraid it may take up too much time away from revising for English and History. However, my back up plan if I am unable to become a lawyer is to become an accountant (and if possible get a double degree in university) so should I stick to SL Maths? I'm good a…

Greetings People, I would appreciate some help with my Maths EE that I am just beginning to start. I have sort of built upon a topic and my advisor says it can be evaluated using deep mathematics integration and would be nice choice. I personally have a passion for Maths and Physics so I thought of doing something that combines both the subject areas. I am thinking of mathematically proving man running at speed of light under certain or limited circumstances inside a particle accelerator. I am currently reading up on Special Relativity in advance. My advisor has told me to learn calculus all by myself to have a greater complicated mathematical approach but an understa…

So after trying past papers (paper 1) and mixed ones (of different years but for paper 1, too) created by my teacher, I noticed that I am always getting around 65%. Sometimes I'd get a 60% or a 70%, and maybe on one occasion a 49% or an 82%. Should I be worried if my mean score is 64%? I mean, for myself at least, Paper 1 is where I have really struggled over the year. I once got 35% in my Paper 1 and 80% in my Paper 2. So if I am aiming for a Level 6, would getting a 64% in my practice be worrying or am I following the right track? Also worth mentioning that out of the 35% that I get wrong in my practices (forgot to mention, they are done under exam conditions), at…

I ABSOLUTELY need a 7 in Maths HL to enter University, and I feel quite capable and within the 7 markbands as regards the papers, without boasting. I've literally sit for at least 3 hours every single day during the last year to do exercises, so I know I will get the 7 in the tests. However, for the IA I feel like it's a completely different story. I had to do it basically overnight. I was sleep-deprived. Did pretty much all my IAs that month, and on top of that I decided to do a very unusual type of work. It was about infinity, randomness language and π. In retrospective, I feel like I was perhaps too bold in my intention, because I really craved that 7. I didn't include…

Hello! I am a rising junior who is getting ready to face the real challenges of IB next year. As the title indicates, I plan on becoming a lawyer. When we were allowed to pick our classes, I picked Math SL, but now I am having cold feet. I usually did well in math, but since I started high school I've slacked off in my classes with little effect on my grades, except in math. I realize I probably don't want to take Math SL, as I feel it will be too much work for me and I will probably slack off. That brings me to my question! What math class do you guys recommend an aspiring lawyer take? I'm leaning towards asking for a switch to Math Studies, but I'd like some input …

Hi, I'm a bit late with my school's deadlines, and I still have to get my Physics SL and Math HL IAs done ASAP. My teacher doesn't really know if the SL and HL samples are taken holistically, or the courses are separated, as this would allow me a little bit of time to finish my IA properly, since I am the only student in the school taking HL. Do you know where I can find the handbook of procedures 2016?

Hello everyone, I will be in Grade 11 next year, I plan on taking IB B&M HL and Economics HL as I want to major in Economics. I am confused because some people suggested that I don't need to take Mathematics SL. They said that it won't be useful for Economics in university. Can anyone help me with this? Should I take Maths Studies or SL? I'll be taking IGCSE Mathematics on May and I expect to get an A. Thanks.

I have no interest in maths (I like dancing ) so I don't think I will be choosing the High Level maths course. Thanks, BongSoldier OUT.

Hello everybody! I want to study medicine in Australia and I was wondering if there are universities that accept studies? I get 4s in math standard without any studying. Due to chemistry hl I don't have much time to study math and therefore my second question is do you think I should take studies and after I finish my IB diploma take an extra course? Would it be better to take studies and get better grades in general because I'll have more time to study and then take an extra course?

Hi everyone, I'm doing IB Maths HL and going to graduate this year & have a question regarding my IA. My IA is very advanced and it involved me going over a graduate papers and filling in all the blanks & assumptions taken by the author (there were A LOT! I find myself filling between two steps with heaps of intuitive explanations & diagrams) and from the result of the paper (end proof), proving another theorem. I wanted to know if it is considered plagiarism? Of course, I'm citing the paper, but does simply making a paper much much more complete not consist of an IA? If so, how can I make it consist of an IA? Thank you! Rebs

Hi, I am taking IB right now and I chose standard level math. However, I am starting to doubt myself because I am not doing so well. I have done two tests of the first two topics and I have got just above the average of my class, where the average is very low. I am getting level 4s at this moment. I have got a pass in IGCSE extended math and with that said, I am not gifted in math. It took me a whole lot of revision and dedication to get what I got in the exam. I had a chat with my mom before school started and we agreed that I should give SL math a shot. One of the big reason why I chose SL math was because I wanted to be a pilot in the future and my parents were the o…

I've introduced my topic showing personal engagement, however I'm really stuck on how to approach the mathematics. I was planning on using geometric sequences to create a model, but how do I even go about doing this. Would this even be sufficient mathematics for SL? Should I first investigate something such as profit and loss and then use those findings to create an ideal model? I really appreciate your inputs on this, thanks!

Hello All, A function is expressed as: y-k=f(x-h) where (h, k) is a translation vector. By drawing x2 and (x-1)2, I can see that the x+1 now takes the y-value of x. But how do we derive this general equation? Surely, it couldn't have been derived by sketching a pair of graphs, and seeing what happens at each point!! Thanks in advance!
