Estimation of Pi The idea is to simulate random x, y points in a 2-D plane with domain as a square of side 1 unit.

Imagine a circle inside the same domain with same diameter and inscribed into the square. We then calculate the ratio of number points that lied inside the circle and total number of generated points. Refer to the image below: Random points are generated only few of which lie outside the imaginary circle. More the. Randomly generated x and y values from a. Range of x and y values is -1 to 1.

Distance between x, y from the origin. Checking if x, y lies inside the circle. Estimating value of pi,.
