Intermediate Value Theorem, The

Synopsis
At 4.00am GMT on Christmas Day 1987 there was a pair of opposite points on the equator with equal temperatures. This was also true on Christmas Day 1986 and will be true at any time and date; it’s a consequence of the intermediate value theorem. Several models and animations are used to establish this and other surprising phenomena. For example a table rocking on an uneven surface can be stopped merely by twisting it through a small angle: the IVT. Animations detail the proof of IVT, highlighting the fundamental concepts required.

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
