“…This example for computing the real roots of piecewise algebraic curve is modified from[3].Let ∆ = {a, b, c, d}be a regular triangulation of rectangular domain ABCD in R 2 , where a = [AOB], b = [BOC], c = [COD] and d = [AOD], where A = (−3, 0), B = (0, −3), C = (3, 0) D = (0, 3) and O = (0, 0), f and g are algebraic curves (See…”
