APPLICATION OF MATHCAD IN TEACHING "ECONOMICAL-MATHEMATICAL MODELS AND METHODS" DISCIPLINE Hotomtseva M. A.

(Belarus, Minsk) It is considering the possibility of using Mathcad in conducting laboratorial practice in economical-mathematical modeling. It is showed that modeling in Mathcad environment allows to assimilate practical skills in algorithmization and programming, mathematical model of the problem essentially consist of the realization of algorithm like a Mathcad document. The using of such advantages of Mathcad like symbolic evaluations and programming allows to unify the algorithm of construction, researching and optimizing different models.
