This change consisted of a 12-inch TFT LCD virtual instrument panel, which replaces the conventional cluster design - instead 'virtual' gauges are displayed where physical analog gauges were previously. The 2010 Range Rover also gained new visual display units as also seen in the new for 2010 Jaguar XJ (X351). This book is especially suitable for students preparing for national or international mathematical olympiads, or for teachers looking for a text for an honor class.The interior of the Range Rover was given a minor facelift, consisting mainly of redesigned and repositioned switchgear (which saw many of the originally BMW era designed items updated or replaced), along with new options never before available for Range Rover. The text contains as selection of 300 practice problems of varying difficulty from contests around the world, with extensive hints and selected solutions. Each chapter contains carefully chosen worked examples, which explain not only the solutions to the problems but also describe in close detail how one would invent the solution to begin with. The emphasis of this book is placed squarely on the problems. The exposition is friendly and relaxed, and accompanied by over 300 beautifully drawn figures. The final part consists of some more advanced topics, such as inversion in the plane, the cross ratio and projective transformations, and the theory of the complete quadrilateral. Another part is dedicated to the use of complex numbers and barycentric coordinates, granting the reader both a traditional and computational viewpoint of the material. Topics covered included cyclic quadrilaterals, power of a point, homothety, triangle centers along the way the reader will meet such classical gems as the nine-point circle, the Simson line, the symmedian and the mixtilinear incircle, as well as the theorems of Euler, Ceva, Menelaus, and Pascal. This is a challenging problem-solving book in Euclidean geometry, assuming nothing of the reader other than a good deal of courage. Euclidean Geometry in Mathematical Olympiads - Evan Chen Summary
