Monte Carlo Method for Approximating Pi
This interactive demo uses the Monte Carlo method to approximate the value of Pi. The square represents a 2x2 area, with a circle of radius 1 inscribed within it. By randomly plotting points and comparing the ratio of points inside the circle to the total points, we can approximate Pi.
