I need help about my maths IA ASAPWatch
I'm making my math HL IA on curve fitting. I found a road on google map so I took the coordinates after that I draw the graph of it now I gotta calculate the length of the road but I don't know what I'm doing. I saw polynomial regression things finding a appropriate function but anyways excel gave me a function of 2nd degree can someone tell me wtf is going on
I started my Maths IA on Orthogophcial projection or Perspective projection in 3D rendering but it is way more complicated than the IB maths and no guide available on the net let alone the examples. Skimmed through two books but also didn´t find any help in it. So now I have to change my topic.
