# Inflection Point

## Inflection Point

Point on a plane curve where its concavity changes directions.

### Examples

• The graphic representation of the function defined by $$f(x) = x^{3}$$ has an inflection point at the coordinate point (0, 0).

• The zeros of the curve that are representative of the sinusoidal function defined by f(x) = cos(x) are the inflection points of the curve:
