Compute PI by Kashi's Method (use iteration, not recursion). Let a regular polygon be inscribed in a unit circle such that each side, an, subtends an arc = 607 2-1 , and let cn be the chord of the supplement of this arc. Then, since = 3, the recursion relation = (2 + Cr-1 )L2 en makes it possible to calculate any desired cn. Moreover, the Pythagorean relation gives a, = (22-c, ) and half of the perimeter, an approximation to , is the product of the length of a side, times the number of sides, 32
