Description
At 4.00am GMT next Christmas Day, the temperatures round the world will be quite surprising: there will be a pair of opposite points on the equator with equal temperatures. This was also true last ...Christmas Day and will be true at any time and date; it's a consequence of the Intermediate Value Theorem. (IVT) Several models and animations are used to establish this and other surprising results. For example, have you ever tried setting a picnic table on an uneven lawn? You can stop the table rocking merely-by twisting it through a small angle: the IVT again. Further animations carefully detail the proof of the IVT, highlighting the fundamental concepts of Continuity and the Monotone Convergence Theorem.;This programme investigates some surprising applications of the intermediate value theorem.
