Which conditions define a critical point of ?
Hints
- The definition constrains the derivatives, not the function value.
- The vector condition and the two scalar conditions say the same thing.
Show the answer
- A. (a,b) = (0, 0)
- C. fᵧ(a,b) = 0
- D.
Why
Critical points have = 0; the function value itself can be anything.
