英文:At a stationary point, the slope of the tangent line to the curve is zero. 中文:在驻点处,曲线切线的斜率为零。 英文:The function has a stationary point at x = 2. 中文:该函数在x=2处有一个驻点。 英文:To find the stationary points of a function, we...
Stationary points of a function are the points where tangent at the point is horizontal or slope of the function is zero. These are called the stationary points because function at these points is neither increasing nor decreasing. We use all the first-order derivatives ...
We give a new method for the numerical calculation of stationary points of a function when it is subject to equality constraints. An application to the solution of linear equations is given, together with a numerical example. (author). 5 refs...
Stationary Point of a Function A stationary point of a function is a point where the derivative of a function is equal to zero and can be a minimum, maximum, or a point of inflection. Stationary points are so named because the function does not increase or decrease at these points. They...
Find the stationary/critical points of the function. g(x,y)=x3−3x2+13y3−4y+10 Stationary Points: Consider a function g(u,v) with variables u and v, then the steps must be followed for obtaining stationary points as: (a) Evaluate gu(u,v) and gv(...
(2) Stationary Points Recall: Increasing and Decreasing Functions A positive gradient means the function is increasing: 0 dy dx A negative gradient means the function is decreasing: 0 dy dx When the gradient is zero then it is a stationary point: 0 dy dx Graph of the derivative The ...

Stationary Points for Parametric Stochastic Frontier Models The results of Waldman (1982) on the Normal-Half Normal stochastic frontier model are generalized using the theory of the Dirac delta (Dirac, 1930), and distribution-free conditions are established to ensure a stationary point in the lik....
