A critical point of a multivariable function is a point where the partial derivatives of first order of this function are equal to zero. Calculadora gratuita de pontos críticos de uma função - Encontrar os pontos críticos e estacionários de uma função passo a passo The function in this example is. 1. To analyze the critical point $(-\sqrt[3]3,-\sqrt[3]3)$ we compute the Hessian $$\left[\matrix{18x+6xy^3 &9x^2y^2\cr 9x^2y^2 &18y+6yx^3\cr}\right]\ .$$ Its determinant is $$9xy\bigl(36+12(x^3+y^3)-5x^3y^3\bigr)\ ,$$ which is negative at $(-\sqrt[3]3,-\sqrt[3]3)$. Free functions inverse calculator - find functions inverse step-by-step The calculator will find the critical points, local and absolute (global) maxima and minima of the single variable function. In single-variable calculus, finding the extrema of a function is quite easy. Examples with detailed solution on how to find the critical points of a function with two variables are presented.
