Several scattered points (x,y) are given on a list. How to get smoothed/splined numerical values of Integral [y^2 dx], slope dy/dx, second derivative d2y/dx2 , and third derivative d3y/dx3 to better (smaller) uniform x- increments ?. Also, how to obtain these as functions of uniformly incremented arc length ?. Thanks in advance.
