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 $(-\sqrt[3]3,-\sqrt[3]3)$. Likewise, a relative maximum only says that around (a,b)(a,b) the function will always be smaller than f(a,b)f(a,b). Just as in single variable calculus we will look for maxima and minima (collectively called extrema) at points (x 0,y 0) where the ﬁrst derivatives are 0. Using the definition of a critical point , find "by hand" the critical points of each of the following functions. Show Instructions. Finding critical points using Lagrange multipliers.
