courbure

(geometry) a symmetrical open curve that is similar to the path of an object thrown into the air passes till it falls back to earth

parabole

a geometric curve formed by the intersection of a plane with two cones, resulting in two symmetrical branches

hyperbole

an S-shaped curve, often used in mathematics and biology, and represents a function that produces a characteristic "S" shaped curve

sigmoïde

a surface in three-dimensional space formed by moving a straight line along a helix

hélicoïde

a geometric shape formed by the region between two concentric circles in a plane

anneau

(geometry) a flat shape with four equal sides in which opposite angles are equal

rhombe

a straight line that a curve approaches indefinitely but never intersects, characterizing the limiting behavior of the curve

asymptote

(geometry) a flat shape with four flat sides, two of which are parallel
