Get the free "Multivariable Limits" widget for your website, blog, Wordpress, Blogger, or iGoogle. The interval can be specified. Come to Sofsource.com and figure out adding fractions, power and plenty additional algebra subject areas In general, you can skip the multiplication sign, so `5x` is equivalent to `5*x`. Define a Function. 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 $(-\sqrt[3]3,-\sqrt[3]3)$. Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. ... Critical points for multivariable functions.
