WebNov 4, 2007 · That has fxx= fyy= 2> 0 but fxy= 3 so D= fxxfyy- (fxy)^2= 4- 9= -5. The only critical point is at (0,0) and, although fxx and fyy are both positive, that critical point is a saddle point. Your "simplification" simply doesn't work. This, by the way, has nothing to do with differential equations so I am moving it to "Calculus and Analysis".
