The Bisection Method

Halve it and keep the half with the sign change: seven halvings turn a hundred possibilities into one.

What this unit covers

Unit 2: Bracketing Methods for Roots of Nonlinear Equations

  1. 1 Location of Roots and the Intermediate Value TheoremThe sign-change trap: if a curve starts below the axis and ends above it, it must cross somewhere in between. · 5 min
  2. 2 The Bisection MethodHalve it and keep the half with the sign change: seven halvings turn a hundred possibilities into one. · 10 min
  3. 3 The False Position (Regula Falsi) MethodBisection ignores how big the numbers are — false position lets them vote on where the root is hiding. · 11 min
