20.05.2020 · The first being from the title, find the stationary points of the function given by f ( x, y) = x ⋅ y 2 We know that we can find the stationary points by letting every partial derivative equal to zero. But this gives f x ( x, y) = y 2 f y ( x, y) = 2 ⋅ x ⋅ y and since y = 0 with the first function, what is the value of x ?

Classi cation of stationary points: . The nature of a stationary point is determined by the function’s second derivatives. Here is a recipe for the classi cation of stationary points. For each stationary point (x0;y0): 1. Determine the three second partial derivatives and evaluate them at the station-ary point: A = @2z @x2 (x0;y0); B = @2z @y2

In general, local maxima and minima of a function are studied by looking for input values where . This is because as long as the function is continuous and differentiable, the tangent line at peaks and valleys will flatten out, in that it will have a slope of . Such a point has various names: Stable point.

Find a second stationary point of f(x,y) = 8x2 +6y2 −2y3 +5. Solution f x = 16x and f y ≡ 6y(2 − y). From this we note that f x = 0 when x = 0, and f x = 0 and when y = 0, so x = 0, y = 0 i.e. (0,0) is a second stationary point of the function. It is important when solving the simultaneous equations f x = 0 and f y = 0 to find stationary ...
