- 4Condition for critical point on a 3D graph
- 5Discriminant (how to determine the nature of critical points for 3D graphs)
- 6If the discriminant is positive at P:Consistent concavity at P:
if fxx > 0, then P is a minima
if fxx < 0, then P is a maxima - 7If the discriminant is negative at P:=> saddle point at P
