The bisection method in mathematics is a root-finding method that repeatedly bisects an interval and then selects a sub-interval in which a root must lie for further processing. derive the secant method to solve for the roots of a nonlinear equation, 2. Solving Linear Programs: The Simplex Method. boundary value problems, which is based on the homotopy analysis method (HAM), namely, the piecewise – homotopy analysis method ( P-HAM). fixed point method in numerical analysis example Education For All L6_Numerical analysis_Fixed point iteration method ANEESH DEOGHARIA 156,066 views.
