Integral \In"te*gral\, n.
1. A whole; an entire thing; a whole number; an individual.
2. (Math.) An expression which, being differentiated, will
produce a given differential. See differential
{Differential}, and {Integration}. Cf. {Fluent}.
{Elliptic integral}, one of an important class of integrals,
occurring in the higher mathematics; -- so called because
one of the integrals expresses the length of an arc of an
ellipse.
Elliptic \El*lip"tic\, Elliptical \El*lip"tic*al\, a. [Gr. ?:
cf. F. elliptique. See {Ellipsis}.]
1. Of or pertaining to an ellipse; having the form of an
ellipse; oblong, with rounded ends.
The planets move in elliptic orbits. --Cheyne.
The billiard sharp who any one catches,
His doom's extremely hard
He's made to dwell
In a dungeon cell
On a spot that's always barred.
And there he plays extravagant matches
In fitless finger-stalls
On a cloth untrue
With a twisted cue
And elliptical billiard balls!
--Gilbert and
Sullivan (The
Mikado: The
More Humane
Mikado Song)
2. Having a part omitted; as, an elliptical phrase.
3. leaving out information essential to comprehension; so
concise as to be difficult to understand; obscure or
ambiguous; -- of speech or writing; as, an elliptical
comment.
