The critical points that i got from this equation

C = x4 - 8xy + 2y2 - 3

is (0,0)

The function is

Thus, and

Now to find the critical points, solve and

This would mean that and .

Solving the second equation, we have

Substituting this into the first equation, we have

Thus, or .

As a result, when:

Thus, your critical points should be , and

Does this make sense? - March 21st 2009, 11:00 PMHakhengkim
