, a. [L. imaginarius: cf. F.
Existing only in imagination or fancy; not real; fancied;
Wilt thou add to all the griefs I suffer
Imaginary ills and fancied tortures? --Addison.
See under Calculus
or Imaginary quantity
algebraic expression which involves the impossible
operation of taking the square root of a negative
quantity; as, [root]-9, a + b [root]-1.
, etc. (Geom.),
points, lines, surfaces, etc., imagined to exist, although
by reason of certain changes of a figure they have in fact
ceased to have a real existence.

1. (Med.) Any solid concretion, formed in any part of the
body, but most frequent in the organs that act as
reservoirs, and in the passages connected with them; as,
biliary calculi; urinary calculi, etc.
2. (Math.) A method of computation; any process of reasoning
by the use of symbols; any branch of mathematics that may
, a method of treating geometry by
defining a point as the center of gravity of certain other
points to which co["e]fficients or weights are ascribed.
Calculus of functions
, that branch of mathematics which
treats of the forms of functions that shall satisfy given
Calculus of operations
, that branch of mathematical logic
that treats of all operations that satisfy given
Calculus of probabilities
, the science that treats of the
computation of the probabilities of events, or the
application of numbers to chance.
Calculus of variations
, a branch of mathematics in which
the laws of dependence which bind the variable quantities
together are themselves subject to change.
, a method of investigating
mathematical questions by using the ratio of certain
indefinitely small quantities called differentials. The
problems are primarily of this form: to find how the
change in some variable quantity alters at each instant
the value of a quantity dependent upon it.
, that part of algebra which treats of
, a method of investigating the relations
of real or imaginary quantities by the use of the
imaginary symbols and quantities of algebra.
, a method which in the reverse of the
differential, the primary object of which is to learn from
the known ratio of the indefinitely small changes of two
or more magnitudes, the relation of the magnitudes
themselves, or, in other words, from having the
differential of an algebraic expression to find the
