In general, Applications and Interpretation covers a broad range of materials, but Analysis and Approaches covers a narrower range in greater depth. Below lists the main topics in each course, by color code from 2014-2020 syllabus Studies, SL and HL (including Further HL). New topics are italicized. HL includes all SL topics of the same course. Common topics in all new Math courses: Algebra: scientific notation, arithmetic/geometric progression, compound interest, annual depreciation, exponents/logarithms Functions: lines, graph of a function, domain/range, definition of inverse, identifying extremas, intercepts, symmetry, zeros, asymptotes Geometry/Tr…

Yup cabso is right...you are truly good at this.!!......I also had a question for you...Becuase I moved a few American schools... and i was never good at maths..actually is the subject i hate coz im really bad at it...but i was wondering if you could still get your IB diploma if you take the lowest Math class.which is Math SL I bet...even tough it was even more confusing with the amercan formula that had a bigger varitey of levels including calculus...and all of that....

I haven't seen any IA tips around so I guess I would share some tips gathered from my Mathematics HL teacher's suggestions, some IBSurvival members' suggestions, my own knowledge and my own experiences. Cover Page Unless this is set by your school, I recommend that your cover page includes: • School Name (e.g. Sekolah Tiara Bangsa – ACS) • School Crest, if available • Subject & Level (e.g. Mathematics HL) • Portfolio Type (e.g. Portfolio Type I) • Portfolio Title (e.g. Patterns Within Systems of Linear Equations) • Candidate Name (e.g. Desy Kristianti) • Candidate Number (e.g. 001863-002) • Examination Session (e.g. May 2012) Header and Footer I recommend that your H…

Here is some advice that you might want to follow right before and during the Math examination. Although most of these things are common sense, I think that putting it all down in words helps. So, 1) Ensure that you have atleast 2 working pens, a ruler, an eraser, two working pencils and your GDC put into your bag the night before the exam. - The last thing you want to do is forget something small and go around begging people for it/ going home to get it right before the exam. 2) Change the batteries of your GDC the night before the Paper 2 exam. - I know this is kind of extreme but after having used the GDC for so much exam practice [hopefully], the batteries might be ru…

Hello people! I have seen Biology, Chemistry and Physics help threads; I figured I would create one for Mathematics too. I'm willing to help any Mathematics student with their problems or doubts. I am sure there would also be some other helpers, so if you have any Math question just post here unless they are questions regarding IA tasks. Questions regarding IA tasks must be posted in the correct IA threads and not here. Questions from textbooks, worksheets or even past year papers may be asked here no matter whether they are for Math HL, SL or even Studies. Please also include which Math level you are taking so the solution and explanation would be suitable with the exten…

IBS has a system set up which allows you to enter in various bits of code and have them appear as mathematical symbols called Tex tags. For instance, rather than writing x^3, you can write . This is a quick guide explaining how to make this work for some of the more common Maths symbols you need for the IB. It may also come in handy as a way to copy/paste in as graphics for IAs, where relevant. For a more comprehensive overview, please take a look at this site: http://en.wikibooks.org/wiki/LaTeX/Mathematics Additional Links (kindly suggested by Chrypton) Detexify - This site contains a white drawing area where you can draw a math symbol that you don't know the LaTeX c…

The growing number of posts, where solutions to internal assessment tasks are given, has unfortunately led me to create a specific rule for this forum. [b]Do not post mathematical solutions to questions about Internal Assessment tasks.[/b] IB rules clearly state that students are not allowed to gain direct help, whether oral or written, in writing their mathematics IA tasks. Thus, even if a student is desperate in proving a statement or finding the correct method to problems, you may not give the answer to him. You may, however, give an answer of general nature (without actual calculation) that will direct a student to the methods required to find a solution. For examp…

I've done research on some universities in the UK to study Veterinary Medicine but none of the ones that I've come across specify if I should take AI or AA, the only requirment being Maths SL and/or the grade (e.g 5 out of 7). Some don't focus on the overal points out of 45 but more on the individual grades of subjects. I've spoken to a few teachers, they said AA would be a better option as it'll give me more opportunities for universities but after receiving my prior knowledge test we did during induction for DP, I did not get a high enough mark and so my maths teacher doesnt recommend AA maths. I'm unsure if I should still take AA maths, I believe that I'm cap…

I’m a year ahead in math at my school and am taking SL A&A as a Junior. I am testing this year. My teacher told me that my next class would be HL A&A and I would take the class but not test. However, that class is notoriously difficult at my school and I’d rather not take it. I’d much rather take the easier non-IB statistics class. So, is 4 years of an IB math class required if I’ve already tested out? Or could I take a non-IB Stats class and still get the diploma?

Hello everyone. Hope you are loving the new year. I plan to start HL math AA next year. Does anyone have any advice for me? Also what textbooks are the best? I need one with good explanations and another one with very hard questions even. I actually like books with questions harder than the exam because if you practice those and get good at it, the exam will be easy for you. Anyway thanks and have a great day.

Hello everyone hope you is are the new year. Does anyone have a PDF copy of the IBID HL math book Analysis and application book. I downloaded this book from Z Library and Ib resources/Ib Repository but the file I downloaded was only about 274 pages. That seems off as the other books like the Cambridge, Haese mathematics and other books are about a thousand pages. Is this the real size of the IBID book? If yes then great but if not, can anyone kindly share the file with me? Thanks and hope you have a great day.

Hello everyone! As a part of my math ia, I am analysing the pharmacokinetic profile of a drug. A part of the pharmacokinetic profile involves finding the area under the curve of the medication's concentration - time graph. I think this area is meant to represent the total exposure of the drug to the paitent's body. This is what it says online as well. In other words, it would be the total amount of drug absorbed by the body. However, I'm not quite sure how this works, as the units used for the y axis (miligrams of the drug in each litre of drug - mg/L) are completely different from the x axis (time in hours or minutes). Multiplying these units would give you (mg*hr)/…

I haev several ideas for a Math AA HL IA, but I'm not sure what application of these ideas I can use. I also take Physics, so I was thinking about doing something with differential equations in Physics. - Taylor series - Differential equations - Integrating non continuous functions (such as 1/x) - Different methods of solving the basel problem I would prefer to do something that focuses on pure math instead of an application, but as I understand most IAs are applications of Math into the real world. Thanks!

Hi, I've had to change my topic for my IA heaps of times now and it is due next week. The current topic I was thinking about doing was how GPS works. I get that it works on trilateration, but I saw somewhere that someone did a HL math IA on it. So I was wondering what kind of concepts do I use if I did my IA on this and how would I make it HL? I'm doing math aa hl btw. Thank you so much!

Hi guys, I am starting to write my math IA on tumor growth modelling and have researched quite a few models on tumor growth. One thing that concerns me that models seem a bit complicated and don't know exactly which models are best for my level of maths. Though I have seen it on the list of suggested topics and I guess it's not high above my level. Please share any ideas and advice, and also good resources you may know about. I would really appreciate this a lot.

Hi everyone. I'm having a little trouble with my Math IA., I would like to do the topic "The Mathematics behind Medical Testing", where I would speak about false positives / false negatives and the probability of getting them. However, I don't know where to get data from. Am I supposed to make up a hypothetical situation / disease and then make fake numbers for it ? Is that even allowed..? I would be using conditional probability to find the probability of a student testing positive for the XYZ disease, actually having the disease. I would be using the conditional probability formula, but I'm finding that the math is very limited (there's not much to do).…

Hi everyone! I am an IB senior and was just finishing up the first draft of my extended essay. My topic is based around models on forecasting the stock market, specifically comparing two models and their effectiveness in terms of accuracy on forecasting the stock market. However, I was running into a few issues when trying to sort out my calculations. As I was working through my calculations I realized that a few of my data crunching calcs needed to be done in R/Rstudio. I was wondering if R is permitted to be used in Math EE's as long as there are significant physical calculations for the methods used in R. Any assistance would be great!

Hey! I was wondering if anyone has done a Maths IA (exploration) connected with sport and calculations around it, can be both HL or SL. I have to write an essay in Maths (for a competition) which is somehow similar to IA (but it's not really about IA), so that's why it doesn't have any specified level of Maths required. I was thinking of calculating something with skiing (or figure skating) cause I'm interested in that and I think I could find some Maths in it. However, I'm not sure how to tackle the topic (I'm in Y1 so we haven't started our IAs yet) and what it could possibly be about. If anyone has done an IA (or another Maths essay) in any of these topics, …

Hello there, I have two questions one is that how much do IB expect from us to write in EE math, since it is really difficult to write up to 3500. second one is that how do plagiarism really works. In math we cannot really change a proof of a theory, so if I took it from a source does it really counts as plagiarism or rephrasing it and citing it counts.

Today I got to know that my school has dropped math HL because lack of teachers and they say that students don’t get above 4 in math HL while most just switch to SL, leaving 1-2 students for math HL (our IB batches are quite small, like 15 students in a batch). So my school is against math HL and our coordinator was telling us that engineering/compsci unis accept math SL (giving a scholarship on merit too) anyway so what’s the point of taking math HL. Is she right? Should I take math SL or should I talk to my head about making an exception for me and letting me take HL? I’ve performed well in GCSE math and additional math (yeah yeah IB is different but I mean that my math…
