Question

If there is a local minimum of a given equation, how do you find the value of the discriminant at that point?

Answer 1

is the local minimum at zero?

Answer 2

no

Answer 3

Do you know the formula for find discriminant?

Answer 4

no

Answer 5

it is sqrt(b^2-4ac)

Answer 6

what's the three space equivalent of that?

Answer 7

if discriminant is positive it means you have two more more solution
0 if only one sol
negative if no solution(imaginary number)

Answer 8

couldn't the discriminant always be either positive or negative if it is not 0?

Answer 9

yes

Answer 10

this is for discriminate formula for (I think) multi variable function

Answer 11

Fxx(a,b)*Fyy(a,b)-Fxy(a,b)^2

Answer 12

Thank you! You're right, I think. In any case, that formula worked.
