Ah, thank you so much for clarifying this for me. :)
I don't really have anyone around me that I can talk to about math, excluding my teacher, and I just had to know! Ah!
Sweet.
I was just doing some homework, and I got to thinking about this.
So if the limit of a function is an imaginary number, does that mean that the limit does not exist? Or that it does not exist on the xy-plane, or what?
I mean...imaginary and complex numbers exist, we just can't graph them...
I found that one, at the very least. :)
The assignment was due today, posting this was a last hurrah, I suppose. Now, however, I'm merely curious as to how to solve it.
Homework Statement
I was given an assignment to find all relative extrema and saddle points of the equation
f(x,y) = 1/3x^4 + 1/2y^4 - 4xy^2 +2x^2 + 2y^2 + 3
I derived the first partial with respect to x and the first partial with respect to y, but when I tried to find where they both...
