"WebTo find stationary points we solve 6 x 2 − 6 x = 0. Factorising to 6 x ( x − 1) = 0 gives x = 0 or x = 1. Substituting these values of x gives f ( 0) = 5 and f ( 1) = 4. So the stationary points are ( 0, 5) and ( 1, 4). Note. Here f has degree 3, its derivative f ′ has degree 2, and so f ′ ( x) = 0 is a quadratic equation. " - Find stationary points of a function

Finding Stationary Points and Determining their Nature

WebGraphically this is a point on the curve at which the tangent line is horizontal. Now consider a function of two variables \(z=f(x,y)\).

These points are called stationary because at these points the function is neither increasing nor decreasing. That is for y = f ( x), d y d x = f ' ( x) = 0 at stationary points. Hence we find stationary point by d y d x = 0 or f ' ( x) = 0.
