Classification of critical points
Find and classify the critical points of \(f(x,y)=8xy-2x^2-y^4\)
Critical points are those "important" points, basically! Google is your friend: http://en.wikipedia.org/wiki/Critical_point_(mathematics).
I know what a critical point is. I don't know what it means to "classify" them.
If I had a region then I would have an interior point and a boundary curve. But no region is given to me. so would they all be classified as "interior"?
"is it a global/relative max/min I would think
ah that makes sense. so like max, min or saddle point?
