1. Torsion of a curveIn the elementary differential geometry of curves in three dimensions, the torsion of a curve measures how sharply it is twisting. Taken together, the curvature and the torsion of a space curve are analogous to the curvature of a plane curve. For example, they are coefficients in the system of differential equations for the Frenet frame given by the Frenet–Serret formulas.
