I have this function and I am looking for the stationary points:
I have the two partial derivatives:
I have already found the stationary points: and
For can we set:
and thus have:
or is this useless because it doesn't satisfy ?

Two things:
1) I'd have to agree that it is of no value because it does not satisfy (E.1)
2) Why didn't you wonder about the other three really obvious suspects (not to mention the infinitely many others) from that last errant exercise?
Please be unconfused. You got it right in the first place. It was only talking about the circle that became confusing. Rule out the circle and you're done.
Of course, (0,1) and (0,-1) were identified before you started playing with the circle, so keep those two.
