The Method of False Position
web.mit.edu › 10 › WebOne such method is the Method of False Position. Here, we start with an initial interval [ x 1 , x 2 ], and we assume that the function changes sign only once in this interval. Now we find an x 3 in this interval, which is given by the intersection of the x axis and the straight line passing through ( x 1 , f ( x 1 )) and ( x 2 , f ( x 2 )).

Choose pre-specified tolerable error e. 5. Calculate new approximated root as: x2 = x0 - ( (x0-x1) * f (x0))/ (f (x0) - f (x1)) 6. Calculate f (x0)f (x2) a. if f (x0)f (x2) < 0 then x0 = x0 and x1 = x2 b. if f (x0)f (x2) > 0 then x0 = x2 and x1 = x1 c. if f (x0)f (x2) = 0 then goto (8) 7. if |f (x2)|>e then goto (5) otherwise goto (8) 8.
