Bisection method to find roots in python

WebThe table below lists situations and appropriate methods, along with asymptotic convergence rates per iteration (and per function evaluation) for successful convergence to a simple root(*). Bisection is the slowest of them all, adding one bit of accuracy for each function evaluation, but is guaranteed to converge. WebThe bisection method procedure is: Choose a starting interval [ a 0, b 0] such that f ( a 0) f ( b 0) < 0. Compute f ( m 0) where m 0 = ( a 0 + b 0) / 2 is the midpoint. Determine the next subinterval [ a 1, b 1]: If f ( a 0) f ( m 0) < 0, then let [ a 1, b 1] be the next interval with a 1 = a 0 and b 1 = m 0. If f ( b 0) f ( m 0) < 0, then let ...
