Learn how to operate each calculator to figure out the project's duration and critical path and slack time for each task. Then, write down the function of multivariable, which is known as lagrangian in the respective input field. How to calculate a critical point? ADVERTISEMENT. The reader should observe that the first constraint \(x + y 1\) requires that the feasible region must be bounded below by the line \(x + y =1\); the test point (0,0) does not satisfy \(x + y 1\), so we shade the region on the opposite side of the line from test point (0,0). Find the critical points of the function f x y z = xy+yzxz +xyz. Solution to Example 1: We first find the first order partial derivatives. . In this example, the point X is the saddle point.
