Definition
Meaning and Definition
In geometry, a point on a curve where the direction of the tangent is indeterminate; a cusp where the curve has a double point and two branches cross.
In mathematics, specifically in the study of algebraic curves, a spinode is a singularity where two branches of a curve meet and share a common tangent. It represents a specific type of cusp or nodal point.
