It was in school that most of us first flirted with trigonometry, simultaneously being handed the scientific calculator for the first time in order to determine the sines, cosines and tangents of angles. For some of us – perhaps its more accurate to say only a few – these strange functions were met with fascination and glee, representing the first real encounter with non-trivial mathematics. In most cases, the presentation of trigonometry is delivered in the context of problems involving triangles, which quite rapidly become rather repetitive and dull. Consequently, many students do not appreciate the crucial relevance and importance of trigonometry in solving more interesting and complex problems, drawn from astronomy, cartography and navigation, to name a few fields. Moreover, merrily determining unknown angles and sides of triangles with full dependence on the calculator, we do not stop to ask how, say, the sine of a particular angle could be worked out without a computing machine, ...

The General Algebraic Modeling System (GAMS) is a high-level modeling system for mathematical programming and optimization. It consists of a language compiler and a stable of integrated high-performance solvers. GAMS is tailored for complex, large scale modeling applications, and allows you to build large maintainable models that can be adapted quickly to new situations. The GAMS System Introduction The General Algebraic Modeling System (GAMS) is specifically designed for modeling linear, nonlinear and mixed integer optimization problems. The system is especially useful with large, complex problems. GAMS is available for use on personal computers, workstations, mainframes and supercomputers. GAMS allows the user to concentrate on the modeling problem by making the setup simple. The system takes care of the time-consuming details of the specific machine and system software implementation. GAMS is especially useful for handling large, complex, one-of-a-kind problems which may requi...
