Regula-Falsi Method
math.iitm.ac.in › public_html › sryedidac = b -. f (b) * (b-a) f (b) - f (a) Now the next smaller interval which brackets the root can be obtained by checking. f (a) * f (b) < 0 then b = c. > 0 then a = c. = 0 then c is the root. Selecting c by the above expression is called Regula-Falsi method or False position method. Algorithm - False Position Scheme.
