Say you had the following function:
I know that the stationary points occur at the point where so the stationary points for this function would be and . How would you classify these points?
I know it has something to do with comparing and .

It is alocal minimum if f(a+h,b+k)>f(a,b) mfor all sufficiently small h,k (not both zero)
It is a saddle point if f(a+h,b+k)<f(a,b) for some values of h.k but >f(a,b) for other values
