Question

what is partial derivative of f(x,y) = x^3 - 3xy^2 + 6y^2

Answer 1

fsubx=3x^2-3y^2
fsuby=-6xy+12y

Answer 2

Hi, do you need to find it in both terms of x and y?

Answer 3

In terms of x: 3x^2 - 3y^2 + 0
In terms of y: 0 -6xy + 12y

Answer 4

yes thanks.. let me take a look and see if I understand

Answer 5

I am trying to find the local extrema

Answer 6

I am having a hard time solving x and y to find the critical points

Answer 7

can you show me how
