Soo, I was wondering if anyone could possibly help me out? I've found some resources but I'm still very confused on how to use them and stuff like that, so if anyone would be willing to lend me a hand, pls let me know as soon as you can, bc ya boi is running out of time due to my own procrastination.

Thank you😭

]]>I asked my teacher about this and she said she can't access the past papers which is why I'm slightly confused

]]>I'm doing the mobius strip for math IA (I'm in AA HL) and currently I have the parameterized equation derived from the torus, I know I need more math in it and definitely some calculus but I'm not sure how to add it because I am not able to find anything online that is comprehensive. ]]>

Currently, I'm very much interested in cryptography and machine learning which are the topics that I want to do my Math IA on, are these viable ideas? Earlier when I talked to my teacher, he said that writing about the Global Positioning System (GPS) would be a great idea, but I'd much prefer the other two topics. What should I do to ensure that I get a high grade while doing something that I actually enjoy?

]]>What do you guys think? Is it really like that? I also have concerns on the mathematical usage as I havent found any calculations apart from how to find Phi.

If you consider its not really a good topic, do you have any recomendations on an interesting topic to write abou that will help me with the graders?

Thank you for reading !

]]>

does anyone have any advice to give me on how to proceed?

(i have minimal knowledge about cryptography)

thank you peeps

The topic i'm looking at currently:

- the more eco friendly formula 1 racing schedule

this topic would possibly relate to Voronoi diagram and graph theory, to minimize distance travel between different grand prix, but on f1 calendar their are around 22 races; so graph theory might be a disaster.

- Genshin impact character damage optimization

this I'm really interested but not sure since it might not relate to the course that much, I believe I could use probability to approach problems such as crit rate and crit damage. but other might just not be about the course.

- monopoly probability

I want to determine which land/block should be the most valuable (people visit more) but through out the rounds the calculation would just be too much. or find the best stategie or equation to determine if a player should or should not buy a land. but Monopoly seems to be a topic that lots of student already used, so not sure should I also use it or not.

thank you for reading, any suggestion or advice would be great.

For my maths IA I have derived my own mathematical proof of Rothe's formulas for the generation of involution numbers. I did not seem to find any such proofs online, I only found the formulas themselves; I came up with a method for both the summation formula and the recurrence relation, however I am also planning on extending this to applications in group theory and coming up with the exponential generating function.

Does anyone know if I would be able to publish this in some small journal? I got the green light in terms of copyright.

Thank you!

]]>Im using coding to create an experiment sample for Personal Engagement and then create two equations- a polynomial equation to predict the sequence and test how accurate it is. The other one is using logs or mod im not really sure and again I test its accuracy.

I just wanted to know how good this is or if its too basic because im not sure if this is even right and what else I could add.

]]>With that in mind I thought I would make a post offering to share some of my resources and advice based on personal experience.

Writing your EE in math is usually discouraged and can be challenging but I personally thought it was very fun since I find math very interesting. I think that if you really like math you shouldn't be afraid to write your EE in math. You should however be careful and make sure you know what you're doing and not be afraid to ask for help.

I wrote my Math IA on celestial navigation using angles with the research question "How can celestial navigation be mathematically modeled to find one’s location on Earth when time and the position of celestial bodies are known?". I'm not sure what my final grade was but the mathematics seems fine and was mainly focused around trigonometry, and vectors with some simultaneous equations.

My EE is about mathematically modeling multiple combined electric fields in a space: "How can the electromagnetic flux density at a point in space with multiple superposing electric fields from point charges be modeled mathematically?". The mathematics I used was mainly vectors and summation, calculus (simplified), geometry, and basic electromagnetic equations in 2D. Solving math problems can be easy but writing an essay where you discuss the results and draw conclusions tends to be somewhat difficult.

If anyone is interested in these topics or has any questions about the Math IA or EE I'll be glad to help. If anyone is having trouble choosing a topic I would also be glad to give advice regarding that as well. Due to the file sizes I unfortunately can't post my papers here but if you DM me with a request I will e-mail you a copy of my paper(s).

]]>Good luck with exams everyone!

Can anyone pls help me??? I only have 2 days left to complete this ia

I was having a lot of trouble picking a topic for my IA, because from what I know we have to pick a topic that goes *beyond* the syllabus? So my teacher suggested the topic of Safe and Effective Medication Dosage (Calculus Modelling). It's great because she'll definitely like it, but would the IB? I've been able to find a lot of papers on the topic - she got it from a different program's Calculus book so, yeah, it's fairly well-known - so I don't know if that would make it less impressive.

I'm also not sure whether the topic would let me go in-depth enough. It seems simple if I take it just on a basis of dosages, time between them, and time for medicine to degrade. Otherwise I would think of applying it more specifically to a certain medicine, maybe the different forms of taking doses, etc. Real-world variables, I mean. But maybe that'll be more biology oriented than math...

So does it seem like a topic worthy of a 17+ ? Suggestions are more than welcome (for this or for other potential topics) Thanks!

]]>Im horribly stuck on my math ia. I procrastinated a lot and now only have a week to send in my first draft. I can’t choose a topic. I saw the topic finding the length of a curved road which seems fairly simple. I might have to go with it but im not sure if it is enough for math hl. Other than this I thought of fractals but seemed too theoretical, I want to have a specific real life situation to work on. Does anyone have ideas? All help appreciated, I really need it.

]]>My teacher has just recently told me and my class about the Math IA. I'm wondering if these following two topics I have come up with would be viable for a possible Math IA, or if I should change course and choose a different topic:

- Correlation IA on the number of human cannibalism cases (from 1900s to present day) and the presence of environmental stressors (environmental stressors are defined as events or things in the surrounding environment that cause stress; for example, lack of food and clean water, physical and mental ailments, etc.)
- Logarithmic IA on the number of rats and the spread of plague/number of disease cases.

My teacher said both were definitely possible, though she looked kind of unsure. I'm not sure myself, honestly, on either of these topics. I picked them because I do have a vested interest in cannibalism and the plague, but I don't believe that's enough to build a working math IA from it. What do you all think? Should I pursue either of these topics, or do something else?

A 5-foot-tall person is walking towards a 7-foot-tall lamppost at a uniform rate of 2 feet per second. Find how fast the subtended angle of the lamppost from the person is increasing when the person is horizontally 1 foot from the lamppost. *Assume the eye level of the person to be also 5 feet for simpler analysis*.

I'm looking to write an IB Math HL AA IA (Exploration) related to Probabilistic Language Models (like predicting future words with n-grams) or anything related to linguistics. I'm having trouble picking a topic though that will have the correct mathematical rigor and sophistication and are able to be structured like an IA. Are there any topics within the field that could make a good IA question that I could research?

Thank you so much!

]]>P.S - I'm interested in subjects like media studies, fashion design, advertising and psychology.

Thank you!!

]]>Thank you

]]>My IA idea submission is due tomorrow and I have no idea what I really want to do, but came up with the idea of optimization using differential equations. I thought of reducing the surface area of packaging in different shapes like sphere and prisms, and calculate the minimum point (minima) through second order differentiation equation. I am also planning to then apply this to different real life examples like Toblerone triangle prism or something like that.

Do you think this is too simple at the level of maths HL because it is just at the level of maths HL in the syllabus? I am ready to discard the idea if the maths involved is too easy for HL. Thanks xx

]]>When it came to brainstorming I had an idea that I ended up pursuing in my Extended Essay (pathfinding algorithms) so I was left with nothing for the IA. I started researching pseudorandomness and a mathematical approach to it but it seems to me I bit off more than I can chew.

There are ideas of recursions, sums and normal numbers but I don't really see how I could apply it to this format.

For example, there is a function which was proved as a way to generate normal numbers which can, in turn, be used to randomly generate numbers but would I have to prove it myself in the paper? Help :(

]]>A statistical exploration on the amount of time required for IAs. For example, the ESS IA "requires" 10 hours of instruction + work time. Math IAs "require" 30 hours of instruction + work time. Obviously ask your seniors and you KNOW it doesn't work like that. I've probably spent 100+ hours on each IA. The way this can be carried out is like you ask alumni from your school and other school, or even ibsurvival, how long it approximately took them to complete a named IA, along with the grade. You don't need anyone's name and stuff, just the subject, time, and grade. Then make a scatter plot, see if there's a correlation between grade and time spent, and carry out a statistical test to see if IB's estimations on time are accurate for someone who's aiming for a 6 and above or something.

Hopefully, that'll help teachers know how long it actually takes to do IB work, and thus how busy and overworked we actually are.

]]>I was wondering if investigating the Fourier Series, and its applications for Noise Cancelling Headphones would be a good and suitable Math HL IA?

I'm not sure if it has the appropriate level of complexity, and also if 'investigating' i.e. explaining how this system works in noise cancelling headphones is going to score highly. Should I try and narrow it down, focussing on a particular brand? Also, how can I make it more 'mathematical' as exploring one theorem may not should a great use of maths?

Has anyone done any work on the Fourier Theorem or series already and found that there isn't much to explore?

If anyone has any comments, tips or advice on this particular field or on the IA in general, I would be very appreciative.

Thanks a lot

John

]]>As of now, I have more or less written out the formulas and explained how the formulas are used but I don't know what to do from there.

Can someone please advice me on how I should go about continuing my IA?

]]>Just want your thoughts on the IA topic - "How far the popular claim that all things from architecture to paintings is based on golden ratio?" - and I want to refute the claim that Monalisa, last supper and roman architecture may not really be based on Golden Ratio.

How do you think this topic is? I was thinking of picking up really good papers and see how they arrived at. And then propose my "thoughts" where they went wrong.

Is this a good HL topic? Please let me know.

]]>So our teacher consistently uses some very strict grade boundaries for AA HL - 90% = 7, 80% = 6, and so on. My question is whether such insane percentages are also required by the IB? The struggle is real here 😅

]]>1) optimizing the volume/surface area of plastic bottles of different shapes (the calculations should be quite ok and I feel like I could link it nicely to some real world applications; from my searches online I have however found that it's a pretty common topic, so I'm not sure if it's better to avoid it),

or 2) looking at spinning tops, most likely at their moments of inertia (I haven't done a whole lot of research on this yet, it seems relatively interesting but much harder than the first one..I'm also not sure if I wouldn't delve too much into physics).

I'm personally more inclined to choosing the first topic, but, as I said, I was worried I could lose points by doing the same thing as many others (I was thinking if I could possibly add some originality to it by looking at other types of packaging, not sure what exactly though..). Would you possibly have any suggestions on other similar topics that I could look into?

Any help will be greatly appreciated!!:)

]]>tl;dr I'm an idiot that chose chaos theory as her exploration topic. I don't get it. Need someone able to walk me through it. Please.

]]>I'm in HL Math AA and I was just thinking about my math IA. I was wondering whether you could do The Painter's Paradox for a math IA, but I wanted to know whether I have do more than just solving the paradox to get at least a 15/20 in the IA.

Thanks.

]]>WHy all the IB math text book have just only with the answer not the worked examples????

pls help me

]]>So I am starting my math HL IA soon and I'm thinking of exploring beats created when two sound waves approach the same frequency but are only slightly out of phase. I potentially want to tie this back to the guitar though an experiment. I have an electric guitar with me but I don't know what to discuss with my results. Any advice?

Thank you
