Therefore we don't have a local extremum at $(-\sqrt[3]3,-\sqrt[3]3)$ either.Thanks for contributing an answer to Mathematics Stack Exchange! Detailed answers to any questions you might have 1) Find the mean of the data. 1. lead to the two critical points $(0,0)$, $\>(-\sqrt[3]3,-\sqrt[3]3)$.In order to qualify the critical point $(0,0)$ we consider the function $\phi(x):=f(x,0)=3x^3$.

The constants pi and The Calculator can find derivatives using the sum rule, the elementary power rule, the generalized power rule, the reciprocal rule (inverse function rule), the product rule, the chain rule and logarithmic derivatives.

Differentiate any single or multivariable function; Find the critical points and saddle points of a function; Calculate the gradient of a function; Identify the local extrema of a function; Find the single, double, or triple integral of a function; Determine the dot or cross product of two vectors; Calculate the divergence or curl of a vector field If the Getting $x=y$ is very useful! $$f_y = 9y^2 + 3y^2x^3$$Then you solve for x, but substituting these two equations into each other.But somehow I ended up with $$x = y$$ and thats not very helpful.Well, $f_x=0$ is $3x^2(3-y^3)=0$, so either $x=0$ or $y^3=3$ (among reals it's $\sqrt[3]3$). Multivariable Critical Points Calculator. This is because say you have two equations: below its horizontal tangent plane at the point.

Solution to Example 1: We first find the first order partial derivatives. $$0=3x^2(3+x^3)$$ 8 and it is a. f_x=9x^2+3x^2y^3$$ Its determinant is $$0=9x^2+3x^5$$ Since $\phi$ assumes as well positive as negative values in the immediate neighborhood of $0$ we can conclude that $f$ does not assume a local extremum at $(0,0)$.To analyze the critical point $(-\sqrt[3]3,-\sqrt[3]3)$ we compute the Hessian It only takes a minute to sign up.Find the critical point of $$ f(x,y) = 3x^3 + 3y^3 + x^3y^3 $$To do this, I know that I need to set $$f_y = 0, f_x = 0 $$So $$f_x= 9x^2 + 3x^2y^3$$ Featured on Meta
