WebA stationary pointof a function $f(x)$ is a point where the derivativeof $f(x)$ is equal to 0. These points are called “stationary” because at these points the function is neither increasing nor decreasing. Graphically, this corresponds to points on the graph of $f(x)$ where the tangentto the curve is a horizontal line. WebIt uses the derivative and power rule for determining the critical and stationary points. FAQ: What are the types of critical points? Critical points are places where ∇f or ∇f=0 does not exist. The critical point is the tangent plane of points z = f(x, y) is horizontal or does not exist. All local extrema and minima are the critical points.
