Method of False Position
An algorithm for finding roots which retains that prior estimate for which the function value has opposite sign from the function value at the current best estimate of the root. In this way, the method of false position keeps the root bracketed (Press et al. 1992).
Using the two-point form of the line
with 
, using 
, and solving for 
therefore gives the iteration
