Critical point of a function of two variables

http://www2.math.umd.edu/~jmr/241/crits.html WebSimilarly, with functions of two variables we can only find a minimum or maximum for a function if both partial derivatives are 0 at the same time. Such points are called critical points. The point \((a,b)\) is a critical point for the multivariable function \(f(x,y)\text{,}\) if both partial derivatives are 0 at the same time. In other words,

WebMar 6, 2012 · In a strict sense, "the" derivative, at a given point, of a function of two variables (as opposed to the partial derivatives) is a linear transformation from to R which can be represented by the vector , the "gradient" of the function f. And, then, the second derivative is the linear transformation from to which can be represented by the matrix.
