Reacting to IB Maths IA (19/20) - How it Got me into the University of Cambridge

In this video I go through my HL Maths IA, and break down how I achieved 19/20!
Some things I cover are:
How to find a topic for a Maths IA
Using personal language to maximise personal engagement scores
Maximising communication scores with short sentences
Trying different things out to maximise "evaluation" score

I'm loving your videos. I've seen all of them. I really want to become an IB teacher, I have a job interview next Wednesday. Wish me luck 🤞

[@MarkosDrakos]

Good luck!!

dude finally not a genius nerd, something i can do , lol was so straight forward on his bs

[@trxle7318]

I’ve recently completed my maths IA for math AA HL and this video was quite useful and did help me quite a bit so thank you for uploading this. Contrary to you, my IA was very much oriented towards physics (as I am an aspiring physics major) and not biology. I investigated the effect of damping on a mass spring system and used complex representation to then graph different functions of different forms of damping (interests me but I know it sounds boring to other people). Anyways thank you for the great upload, I’ve been enjoying your content as of recently and it is very useful.

[@MarkosDrakos]

Wow, that's really interesting! I'm glad you found my video useful, and good luck making it into Uni for physics!

[@trxle7318]

@@MarkosDrakos thank you so much. Keep making great and useful content please!

[@zeynepaslan5164]

I need to do something about physics too, can you help me?

[@trxle7318]

@@zeynepaslan5164 I can try and give you some ideas. If that’s what you are looking for

Its so interesting to me, i made what is the optimal strategy for 2019 austrian race

[@Jyoon.b]

Welcome back🙌 🙌 Can you also make a video about the Extended Essay? I am currently really struggling to find a topic which will fill the 4000 word requirement. Looking at my listed ideas, all of them sound too straightfoward or far beyond my level.

[@MarkosDrakos]

Great suggestion! I'll try to make one soon!

[@user-ce3tt4cf5m]

wait, so ur confused by the experiment and there is a big af error but u still got 7? Does the outcome count so much? Cuz im working on my phy is right now and the data are inaccurate, should i devote more time on the data or i should deal with an excellent conclusion and improvement of the experiment in the evaluation part?

[@patronus7153]

Hey great video!! im taking math HL to (AIHL), and i have two topics in mind. Could you tell me which is better? thx TOPIC 1 -Finding the velocity of the shuttlecock upon a smash, and the angle of contact with the racket. TOPIC 2- Analyzing the Impact of Racket Dynamics on Shuttlecock Velocity in Badminton (seeing how smashes from different parts of a racket change velocity)

[@arnavbansal348]

the second one seems better

[@doncela7729]

Hey could u send a pdf of your math IA? i enjoyed it and im doing something relatively similar and i would like to see it as reference. Thanks! 😼👍

[@user-nv4eq5cw2j]

The music in the background is really changing my point of view. It's so strange... What is the name of the piece?

[@FrequencyOfAll]

So true right?? Same thing happened to me and I decided to look at the comments to see if anyone can relate.

[@user-dg3bd1jk8j]

I have a question. To calculate the surface area of the villus one should find the function to model the shape of the villus, and use the surface area integral formula to rotate 2pi radian about the y-axis to get the SA of a solid of revolution. You used integration to find the area under the curve and multiplied by 2. Did you assume that the villus was flat?

[@MarkosDrakos]

Yes, I assumed the villus was flat, because although they aren't really flat in live animals, the villi I measured were in fact flat. To be honest, I probably could have assumed them to be perfectly round, but I thought I would need to do some complex 3D integration (although your proposal makes a lot more sense, not sure what I was thinking), so I decided to stay away. Hope that explains it!

[@indisguiseofyou]

OMG this is me stressed about turning in my maths IA due soon...

[@NguyenPham-ty4vp]

hi. may i ask if your math course was AA or AI?

[@MarkosDrakos]

If you have any questions, let me know!

Thanks!

could not have worked a Lagrange interpolating polynomial ?

[@MarkosDrakos]

I suppose, not sure though, haven't done hard maths in a while now...
