All rights reserved. An algorithm is described for approximating a function F(x) on a finite interval Ca,b] whose second derivative is of constant sign on (a,b) by a continuous piecewise linear function, with any desired accuracy. Given a positive number e, the algorithm finds a continuous piecewise linear function L(x) = m^x + b, \u3c X \u3c xit i = 1,2,. ,n where a =
