  1. So I am entering my second year as a DP student which is both exciting and unnerving due to the shear amount of work there is to do. That being said my math teacher over the summer wanted us to finalize our math IA topics. I have narrowed it down to two potential topics which are the geometry of ice hockey or how does listening to music affect ones ability to solve math equations. Thanks so much, Maddy
  2. I am am work on my mathematics extended essay, and I want to do it on: 1. Coming up with a general formula for the volume of the five Platonic Solids (I need to know from other mathematics higher level students if this is two simple). 2. The proof(s) for Euler's polyhedron formula. 3. The Travelling Salesman Problem (not sure how much math is involved as opposed to computer science). I am most interested in the first but willing to drop it if it is too simple. I am also open to suggestions of other interesting topics in geometry (the subject I have the most interest in). I want to get some work done before the summer break ends in about 4 weeks, so I could really use some advice (especially considering my adviser has gone incognito).
  3. I am really passionate about math and cars, so I decided to do my IA on racing lines and mathematical approximations of them. The trouble is, I am lost as to how to start. I don’t know how to approach this (should I start with a single corner and try to come up with a line for it?), and furthermore, I can’t prove that the line is the best/better; that would be physics. Should I switch topics or could I save this topic, as it really interests me?
  4. Hi all, I just wanted to know how difficult it's going to be for me to study and succeed in IB. I'm currently studying in grade 10 and I'll most probably start studying according to IB's curriculum next year. I'm currently studying the Holt McDougal Modern Chemistry, English Literature/writing, Biology, and Phyiscs. The McGraw Hill Algebra 2 on top of social studies, Farsi literature/writing and Arabic. I find all of the subjects I'm studying relatively easy (except Farsi. Even though it's my mother language), and I aced all of my finals last term. But I'm kinda stressed to be studying IB as I have no idea about the difficulty level. The hl subjects that I'm gonna pick are biology, chemistry, Farsi and English (I have no idea whether it's gonna be A or B; it's mandatory to study Farsi and English hl at my school) I want to study medicine and I looked at dozens of university admission requirements for the said course; most of the universities I'm interested in require a minimum of 6 in bio hl and chem hl on top of an overall score of 38/45. As I said, I just want to know how much energy I'll need to exert on my studies and how difficult it'll be to meet the mentioned requirements. Your insight would be appreciated! Edit: Do I need to study physics as wrll to get into medicine? I'm already picking Math sl so not sure how that'll work.
  5. Hello, Could anyone send their end of unit tests for maths hl? I want to use them to practice. Would be really helpful. Please
  6. Hello people, I know I will sound crazy/weird, but is it possible to self-study HL mathematics? My school does not teach the HL math, and so I am 'stuck' with SL. I really enjoy maths and I am quite pretty good at it. Also, I want to be a chemical engineer, so HL Chem, Phys, and Math are highly recommended. I am already doing HL Chem and Phys, which is satisfactory for most of the universities, but I really feel like I should also do HL Math. Thank you for your answers
  7. Hello everyone, i am a Math HL student and our teacher is askingus to creat topic proposals for our IAs. Since the level of mathematics used is very important, i want to apply calculus in my ia but i couldnt think of an interesting topic similar to that of modelling rainfall in the sample IAs. So id like to ask for your help and suggest some interesting topics that uses calculus. Thank you!
  8. 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
  9. 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)
  10. Long Post I am in Year 1 taking Mathematics as my subject for the extended essay. Initially i decided to use rotation of conic sections as my topic for my EE but i decided to change my topic again right before my IRS is needed (bc i dont feel motivated anymore on the old topic). Now, i am still trying to think of a new topic so that i can start writing next year. So far i read a Sample EE that garnered 32/36 points. It is about optimizing the distance of the kick of a ball from the conversion point to the try line in rugby considering only the plane parallel to the ground. The EE was easy to understand and as it simply defined the diagram and applied trigonometry, functions, and calculus(derivative) to look for the optimal distance and angle. Along with this method, he also used Circle theorems to achieve the same result. This EE kind of inspired me because it is simple yet his investigation is profound and he had a lot to discuss. Because of this, i thought of switching to the topic of applying maths in sports. One of my considerations is soccer or football as it is closely related to rugby as well as ice hockey since it doesnt deal much with gravity, but alas i dont play soccer, football, or ice hockey so it may not benefit me to look into this (but i am willing to look into these if it is simpler) Another one is table tennis where i thought of looking into the finding the range of angles wherein when hitting the ball, it would land and the maximum location(edges of the table) or near the net. One problem i encountered with this problem is that there are multiple variables regarding defining where the farthest and shortest trajectory of the ball with respect to the racket, how i hit the ball: angles along x and y, position of ball on the table, height where i hit the ball, gravity, spin on the ball, velocity etc. Last problem is how i will pattern this as a math EE as physics concepts are used here as well (projectile motions, angle of incidences etc). in short, id like to ask your insights and possible remedies to my problem on 1. Concepts in sports where i can apply mathematics 2. How to deal with the plethora of variables that can be seen in the topic 3. math concepts i can use to tackle it the table tennis problem 4. how to tackle the physics here mathematically, any advice Hope you guys can help, im sorry for the long backstory and the very demanding questions.
  11. I'm done with my math hl ia but it involves a lot of 3d geometry and stuff. I think I want to write it by hand I have a very neat handwriting and I can also draw the shapes. Can I do that or would it effect my grade negatively?
  12. Currently, I am a bit confused. Looking over the extended essay May 2018 guide I see that the title of the essay cannot be stated in the form of a question (I take that to mean that it also cannot be the research question itself). However, in the mathematics section of the guide it says that "In mathematics, the title of the essay must be in the form of a question" (taken directly from the guide). Then, they proceed to give an example of an essay title when describing how you must explain the title early on, but the example they give is not in the form of a question (they give the example "Methods for approximating Π throughout history"). So, that begs the question, should the title of my maths EE be my research question itself, or just a regular title (a statement)?
  13. Hello all! My extended essay is due Sunday. I am doing one in maths, and I have spent quite a lot of time on formatting. However, I just reviewed the IB Extended Essay Guide for May 2018 exams, and apparently double spacing is required in the formatting. If I do this, then my entire formatting system will be messed up and it will look weird (I currently have it set to 1.5). Is this requirement wavered for math papers? How much will I be marked down if I keep it at 1.5 spacing even if making it double spaced would make the formatting look worse in general? Also, as a side-note, how does the electronic turn-in detect when the 4000 word limit has been reached? Does it know when there is a parenthetical citation and to exclude that? Thank you!
  14. Hi! Having completed Math SL and scored a 7 on the exams, would math HL be an okay transition in terms of difficulty/understanding concepts?
  15. Hi guys, As I want to study economics at a selective university (in U.S) in the future, and I cannot stand taking Math HL at the moment, would it be sufficient to take Math SL combined with AP BC calc? I find Math SL very easy and score 6's/7's frequently (this is since I am repeating one year of the IB), so how hard would it be to shift focus during IB (repeated) year 1 and really study BC calc for almost a semester to take BC exams in spring? In this way I can compete with stronger applicants without having to struggle through the other than calc material in HL Math? Thnx
  16. Hey guys, I'm currently in IB1 and I should be starting to find a topic for my EE. My first choice of subject was Business & Management, and I've already interviewed a company, which wasn't very successful. I have second thoughts on my subject choice and I was thinking of changing to Mathematics. I study Maths SL, and I thought I could do my essay on which university I should choose. My research would be on the employment rate, drop-out rate and graduate salary of a range of universities. Using decision trees I would find which gives the highest chance of the highest income in the future, and that will be the winner. Do you guys think this is an appropriate topic for a Maths EE? Is it advanced enough? Is it a good idea to even change subject? Thanks for your help!

  25. Why not only rely on past papers? In my opinion, the best preparation with past papers is not to look over mark scheme. Essentially, as the name suggests, mark schemes only aim to aid teachers to mark student’s work on his paper. Not only does it lack with the detailed explanation, but also students lose their opportunity to encounter real IB style questions if they rely too much on mark scheme. For section A questions it relatively gives a good explanation; for Section B questions, however, when things get lengthy, explanations tend to be very concise and often do not make sense for students. It solely aims to guide teachers to base their grading criteria; it is not built for a model of ‘worked solutions.’ I encourage students more to discuss their solutions with friends. Also, IB community is very strong among students via internet, such as IB survival and IB Facebook group page. It’s a good place to start a discussion. Let me give you an example why you should avoid the habit of relying your study with mark schemes: Example: This is one of my favorite questions from IB HL. It not only tackles on definition of functions, but also it requires students to understand the concepts on Topic 1 and apply their skills to ‘unseen’ questions. If we look at Part (d) (iii), it asks about giving area in terms of a certain function A. The first part of the questions asks us to find out the relation between Fn and its inverse; here students are required to know what inverse relation is. For the geometrical interpretation, functions that are inverse to each other are symmetric along y=x. Then the second part tests our inequality skills with algebraic and geometrical interpretation: For Part (d), if you realize in the square box of 1 by 1, Fn is less than x, which means it is below y=x from 0 to 1, and since we know its inverse must be symmetric by y=x, the inverse must be above y=x. From this aspect, we can draw a random 1:1 function and work with the area to derive an answer. I believe this is how a student should approach to this type of question, since this ‘interpretation’ of function’s inverse with its algebraic property of composition and geometrical property of symmetry is the key for the unseen question. Let us compare our approach with the mark scheme of the question: As you can see, it’s painfully concise, and students cannot obtain their logical processing of this question from the mark scheme. Yes, when you apply the numbers and methods given by the mark scheme you could get the answer. But you will lose the essence of ‘interpretation’ skills as well as the half-independent attempt on this nice question. You can always elaborate your answer if your logic is correct; that is one of the greatest tactics for IB maths exam. PARTIAL mark!
