Hello everyone, I want to do my Math IA about the nabla (or del) operator used in vector calculus. I'm interested in this because I'm going to study physics at uni and I heard that physics students will need to learn this at uni. So that is a factor that will keep me motivated to do this. However, I don't really know where to go from here. Should I just base my IA on explaining what nabla is and deriving it? Or is there anything in particular I can base my IA on? Thank you.

Could anyone please inform me what the required length for the Exploration is? Also how could one show personal engagement with the topic?

Hello, I'm in my second year of the IB, and we have to start defining our theme for the mathematical exploration. I don't know exactly what do we have to do, I know we have to relate it to numbers or stadistics. And as the teacher said we could choose a topic of our preference, I was thinking if there was a suitable Theme in the area of biology or architechture, perhaps chemistry. I have plenty of difficulties with complex algebra, so I REALLY need your help in the choosing of the topic and would be more than grateful if any of you help me with this issue Just in case you need to know, my sub
