My Solution for Parabolic Arc Length: https://www.codewars.com/kata/562e274ceca15ca6e70000d3/train/rust
We want to approximate the length of a curve representing a function y = f(x) with a <= x <= b. First, we split the interval [a, b] into n sub-intervals with widths h1, h2, ... , hn by defining points x1, x2 , ... , xn-1 between a and b. This defines points P0, P1, P2, ... , Pn on the curve whose x-coordinates are a, x1, x2 , ... , xn-1, b and y-coordinates f(a), f(x1), ..., f(xn-1), f(b) . By connecting these points, we obtain a polygonal path approximating the curve.
Our task is to approximate the length of a parabolic arc representing the curve y = x * x with x in the interval [0, 1]. We will take a common step h between the points xi: h1, h2, ... , hn = h = 1/n and we will consider the points P0, P1, P2, ... , Pn on the curve. The coordinates of each Pi are (xi, yi = xi * xi).
The function len_curve (or similar in other languages) takes n as parameter (number of sub-intervals) and returns the length of the curve. You can truncate it to 9 decimal places.
