Authoritative and reliable, this is the ideal reference guide for students of mathematics at school or in the first year at university. Many entries have been added for this new edition, expanding coverage in the area of computing, including entries on Linear Algebra, Optimisation, Nonlinear equations, Differential equations, and others. More biographies of prominent mathematicians are also added, including Nobel Prizewinners and Fields' medalists. Terms used in first-year university courses, e.g. Lorenz attractor, Linear programming, Liouville numbers, etc., bring the new edition right up-to-date. The dictionary covers both pure and applied mathematics as well as statistics, and there are entries on major mathematicians and mathematics of more general interest, such as fractals, game theory, and chaos.
