Inflection Point - Wikipedia - en.wikipedia.org  ## Metadata - Author: **en.wikipedia.org** - Full Title: Inflection Point - Wikipedia - Category: #articles - Tags: #calculus #mental-model - URL: https://en.wikipedia.org/wiki/Inflection_point ## Highlights - In differential calculus and differential geometry, an inflection point, point of inflection, flex, or inflection (British English: inflexion) is a point on a smooth plane curve at which the curvature changes sign. In particular, in the case of the graph of a function, it is a point where the function changes from being concave (concave downward) to convex (concave upward), or vice versa. - Tags: #maths #mathematic
