  Abstract: Detailed analysis of Newton’s method for finding a zero of sin(x) located at x = Pi, has led to our discovery of a highly efficient recursive method for computing Pi based on the convergent expression x (n+1) = x(n) + sin(xn). This recursion is derived using a geometric analysis of Newton’s method. In addition this geometric analysis proves the surprising result that for any value of x such that in the interval [Pi/2 3Pi/2] that Pi = x + arcsin(sin(x)).
