Arc Length of a curve (function) - Exact & Estimated value
Move sliders a and b to change the position of points A and B respectively. Slider n changes the number of segments used to estimate the arc legth of the curve. If n is big then more points are used and the line segments are very small. By adding all the line segments we estimate the arc legth of the curve. You are also given the exact arc length found by integration. You can also change the function f(x).
