...point at which the tangent intersects the curve, or at which the curve changes from convex to concave, is called a point of inflexion, or, a point of contrary flexure. The analytical indications of such points will be more fully inquired into, when we come to speak of... | |

...Sometimes the curve after being convex to the axis suddenly changes its curvature, and becomes concave, the point at which the change takes place is called a point of inflexion, or of contrary flexure. If the tangent at this point be produced, one branch of the curve will be above... | |

If a curve change the direction of its curvature,...which the change takes place is called a point of contrary flexure, or a point of inflexion. To determine such points we have only to refer to Art. 64,... | |
