Multivariate Function Conditional Extreme Value and Its Application
Abstract:The extreme value of multivariate function has an important status in the differential science of multiple functions. This paper mainly introduces the extremum of function of many variables and methods. For example: Elimination method, the Lagrange multiplier method, standard substitution method, inequality method, gradient method and in combination with number form and so on. It also discusses the multivariate function extremum in such aspects as an inequation, production, sales and application. This paper, we focus on the inequality method for the extreme value of multivariate function and its application.
Key words: Multivariate function; Extremum;Condition Extremum
