Solving Equations − Bisection Method


equations obtained in real life by people such as scientists and engineers often are not easy to solve.

algebraic techniques such as transposing terms, factorising and using the quadratic formula are not suitable.

another method is to use numerical methods which are available to approximate an answer or root of the equation to a certain level of accuracy.

two such methods, studied in this course, are the bisection method and the newton-rhapson method.

Key Skills

  • use the bisection method to solve non-linear equations
  • have a geometrical and graphical understanding of this method


root, iteration.
