CONSTITUTION:A camera 1 of the automatic inflection point reading system is mounted on the x-y driving device, and a computer 3 is connected to this camera 1. The graphs and the graphic lines on a drawing sheet 2 are image picked up with this camera 1 and the relative brightness of a ...
Eq. (7.36) is the breakthrough tangent, a straight line that passes through the x-axis at Sw = Swi and has a slope equal to the derivative of the fractional flow curve at Sw = Swf. The breakthrough tangent (Fig. 7.8) can be drawn by hand on graph paper or computationally using a...

So: f(x) is concave downward up to x = −2/15 f(x) is concave upward from x = −2/15 on And the inflection point is at x = −2/15A Quick Refresher on Derivatives In the previous example we took this: y = 5x3 + 2x2 − 3x and came up with this derivative: y' =...
This graph shows a change in concavity, from concave down to concave up. The inflection point is where the transition occurs. So let’s talk a little about concavity first. Concavity Concavity is about curving. We say that a function y = f(x) is concave up (CU) on a given interval ...

For a continuous function, an inflection point occurs on a graph where a function changes from concave up to concave down. Inflection points occur where the second derivative of the function is equal to zero or is undefined. Once points are located where the second derivative ...
