The '''curve''', also in mathematics called a '''curved line''' in theoretical and applied mathematics texts is the mathematical object similar or different to the axial straight plane [[line (geometry)|line]]s, the curved line is not a straight line but may be a [[function]], or the curved line may be part of a non straight plane (nonrectangular object), or part of a sphere or spherical object, or a ''curved plane'', etc., and there too is different (it is "not opposite", ie not perpendicular or parallel) to [[Linearity|straight]] lines that are part of straight planes but for some functions may be projected to a straight plane into straight planes.
In axial spheres and curved spherical objects, lines maybe defining "the objects geometry".
