Question

Stationary point is a where function f(x,y) have

Answer 1

Step-by-step explanation:

As we said in the previous subsection, the tangent plane to the surface z = f(x, y) is horizontal at a stationary point. A condition which guarantees that the function f(x, y) will have a stationary point at a point (x0,y0) is that, at that point both fx = 0 and fy = 0 simultaneously.
