Ms. Franklin earned a Bachelor of Administration in Economics from McMaster University in Ontario. Define point of inflection. Inflection Point. Climate change. Let's work out the second derivative: The derivative is y' = 15x 2 + 4x − 3; The second derivative is y'' = 30x + 4 . If the third derivative is zero, we do not have a point of inflection. In this lesson we define the point of inflection. The degree of consolidation was estimated to be 70% at the inflection point. One characteristic of the inflection points is that they are the points where the derivative function has maximums and minimums.

Inflection points in differential geometry are the points of the curve where the curvature changes its sign.. For example, the graph of the differentiable function has an inflection point at (x, f(x)) if and only if its first derivative f' has an isolated extremum at x. Search.
