How to get a 7/7 on your Math HL IA Analysis and Approaches

Heyyy,
I made this video many moons ago, but after watching it a year later, I thought it had some good advice. If you're a rising senior, it is a VERY GOOD IDEA to get a head start on your IA's over the summer.
Anywayyyy, I wanted to give a small disclaimer. If anything in this video contradicts any advice or instructions given by your teacher (or the IB) please listen to your teacher, not me.
BIGGEST TAKEAWAYSS:
Read the rubric and know exactly what is expected: mrsmithsibwebsi...
Choosing a topic: USE YOUR TEXTBOOK. The word problems show you how to apply the math you are learning and are basically like mini IA's. You can also look up how your interests relate to math (music, dance, social media, baking....). If you are passionate about your topic, it will make writing the IA more bearable.
The best textbooks are:
PEARSON:

HAESE MATHEMATICS:

Best HL topic (in my opinion): DIFFERENTIAL EQUATIONS! Your topic has to be HL or beyond. In Analysis and Approaches, DE's are HL and they have so many real world applications (especially in the natural sciences). Since I love bio and pharmaceutics, my IA was about a biological application of diff eq's. In the IB there are three types of first order DE's you need to know: ones where you use integrating factor method (this is the one I did), separable, and homogenous. If you haven't got to DE's yet but have done integration, it is worth learning them if you find a really cool IA idea.
I mentioned a word problem that talked about water draining from a tank. Here is a video that could help you: • Time For Fluid To Drai...

Wish I would've seen this before my IA :((((

LOVE THIS

Hello sister, I love your IA topic and I hope to do something similar, can I reach out to you to ask some questions? If yes, how I can do that? Thank you so much and I love your video!

[@Lin-fn1qy]

this is so helpful rn as I am preparing for my IA purposal...for the differential equation, did you come up by yourself or was it found in some research?

[@martapantin2501]

Hi! I originally found this diff eq in this article: sites.northwestern.edu/recalculated/2019/05/05/calculus-in-medicine/.
I did some additional research because there was some variations of the equation that I found online. While the constants may vary across different sources, the key idea here is that the derivative for concentration, dc/dt, is related to the difference in the change in absorption and elimination: da/dt-dr/dt (I used r to represent elimination).
That is, dc/dt=K(da/dt-dr/dt), where K is some constant. You may look up online different diff eq's and see which constants best fit your model. I did mine based on half-life of amoxicillin.
If you like math in pharmacology or organic chemistry, I am sure you can find similar concepts online.
Hope this helps! Praying for you :)
xo,
Marta

Any chance we can see your IA?
