In differential calculus and differential geometry, an inflection point, point of inflection, flex, or inflection (rarely inflexion) is a point on a smooth plane curve at which the curvature changes sign.
Symbols save time and space when writing. Here are the most common geometrical symbols: Example: In ABC, ∠BAC is ∟. Is really saying: "In triangle ABC, the angle BAC is a right angle" Naming Angles. For angles the central letter is where the angle is. Example: ∠ABC is 45°. The point "B" is where the angle is.

An inflection point occurs when the sign of the second derivative of a function, f"(x), changes from positive to negative (or vice versa) at a point where f"(x) = 0 or undefined. Thus, the process for determining the inflection points of a function are as follows:
3 days ago · An inflection point is a point on a curve at which the sign of the curvature (i.e., the concavity) changes. Inflection points may be stationary points, but are not local maxima or local minima. For example, for the curve y=x^3 plotted above, the point x=0 is an inflection point.
Dec 21, 2020 · Of particular interest are points at which the concavity changes from up to down or down to up; such points are called inflection points. If the concavity changes from up to down at x = a, f ″ changes from positive to the left of a to negative to the right of a, and usually f ″ (a) = 0.
