Ill Conditioning in Linear Equations

Synopsis
Examines two problems, both of which involve solving three simultaneous equations in three unknowns, and which lead to very suspicious answers. Trouble arises in the solutions for two reasons. In the first problem, the equations are slightly inaccurate but their solution is widely inaccurate. The second problem again arises due to slight inaccuracies in the equations, but these inaccuracies are introduced by rounding errors made while working out the solution. A method known as partial pivoting is intrdouced to minimise the effect of rounding errors introduced during solutions.

Notes
NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
