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 involve calculation .
[
1913 Webster ]
{
Barycentric calculus },
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 conditions .
{
Calculus of operations },
that branch of mathematical logic that treats of all operations that satisfy given conditions .
{
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 .
{
Differential calculus },
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 .
{
Exponential calculus },
that part of algebra which treats of exponents .
{
Imaginary calculus },
a method of investigating the relations of real or imaginary quantities by the use of the imaginary symbols and quantities of algebra .
{
Integral calculus },
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 expression itself .
