aminzairi 3 Report post Posted September 7, 2017 Hello i've decided to do my math ia on finding the length of a curved road These are the steps i need to follow to find the length of the road : Find the road on google maps Find a curve that fits the road but i don't know ho to fit the curve into the road by polynomial regression and matrices next i need to find the arc length through calculus does anyone knows or ever did a math ia on the topic pls reply im in dire need of help idk what to do here's a link to a file explaining the steps to find polynomial regression : http://web.iitd.ac.in/~pmvs/courses/mel705/curvefitting.pdf i dont understand the part where the person mentioned about least squares approach regarding polynomial functions and how she derived the formula Share this post Link to post Share on other sites

You need a reference to be able to compare those two methods. Edited October 2, 2017 by tim9800 1 Share this post Link to post Share on other sites

I was hoping I could have a look at your IA for reference. Please let me know if you don't mind. Thanks Share this post Link to post Share on other sites
