👉 Rosulate is a term used in mathematics, specifically in the field of algebraic geometry. It refers to a specific type of curve that can be defined as a union of two lines that are both tangent to a given point on the curve. The term "rosulate" was introduced by French mathematician Évariste Galois and has since been generalized to any kind of curve in algebraic geometry, including curves defined by polynomials. The word "rosula" is derived from the Latin word
