The Plateau Curve

The Plateau curve is also called the curve of Joseph Plateau, after the blind Belgian physicist who discovered that a curved wire frame dipped in a soap solution forms “beautiful curved surfaces” [1].

The Cartesian equation for the Plateau curve is:

Where m ≠ n. If m = 2n, the curve degenerates to a circle centered at (1, 0) with radius 2 [2].

The Plateau of a Curve

A plateau curve (no capitalization) refers to a curve with a rapid rise, followed by a leveling off; the flat region that follows is called the plateau of the curve. Roughly speaking, curves with this form have the equation [3]
equation curve plateau

plateau of a curve

A plateau curve representing the variation of counting rate with voltage.



This type of curve has many uses in science and engineering. Plateau curves are often seen in models of high voltage, where they can help determine optimal input voltage [4]; The section of a Geiger Counter is characterized by the plateau curve [5]; there is a sharp ramp up when a Geiger tube turns on, followed by a plateau. In mechanics, the curve can model a flow curve of steady shear stress vs. shear-rate [6]. In biochemistry, the plateau curve models an enzyme-catalyzed reaction rate of a substrate as a function of the concentration of the substrate [7].
