hyperbolic function

any of a group of functions of an angle expressed as a relationship between the distances of a point on a hyperbola to the origin and to the coordinate axes. The group includes sinh ( hyperbolic sine ), cosh ( hyperbolic cosine ), tanh ( hyperbolic tangent ), sech ( hyperbolic secant ), cosech ( hyperbolic cosecant ), and coth ( hyperbolic cotangent )

hyperbolic geometry

the branch of non-Euclidean geometry that replaces the parallel postulate of Euclidean geometry with the postulate that two distinct lines may be drawn parallel to a given line through a point not on the given line

hyperbolic paraboloid

a paraboloid that can be put into a position such that its sections parallel to one coordinate plane are hyperbolas , with its sections parallel to the other two coordinate planes being parabolas
