### Index

#### Barycentric calculus

• a method of treating geometry by defining a point as the center of gravity of certain other points to which coëfficients or weights are ascribed.

#### Biliary calculus

• (Med.), a gallstone, or a concretion formed in the gall bladder or its duct.

#### 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

• noun the calculus of maxima and minima of definite integrals
##### WordNet
• a branch of mathematics in which the laws of dependence which bind the variable quantities together are themselves subject to change.

#### Differential calculus

• noun the part of calculus that deals with the variation of a function with respect to changes in the independent variable (or variables) by means of the concepts of derivative and differential
method of fluxions.
##### WordNet
• 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.

#### functional calculus

• noun a system of symbolic logic that represents individuals and predicates and quantification over individuals (as well as the relations between propositions)
functional calculus.

#### Imaginary calculus

• a method of investigating the relations of real or imaginary quantities by the use of the imaginary symbols and quantities of algebra.

#### Infinitesimal calculus

• noun the branch of mathematics that is concerned with limits and with the differentiation and integration of functions
calculus.
##### WordNet
• the different and the integral calculus, when developed according to the method used by Leibnitz, who regarded the increments given to variables as infinitesimal.

#### Integral calculus

• noun the part of calculus that deals with integration and its application in the solution of differential equations and in determining areas or volumes etc.
##### WordNet
• 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.

#### predicate calculus

• noun a system of symbolic logic that represents individuals and predicates and quantification over individuals (as well as the relations between propositions)
functional calculus.

#### propositional calculus

• noun a branch of symbolic logic dealing with propositions as units and with their combinations and the connectives that relate them
propositional logic.

#### Renal calculus

• noun a calculus formed in the kidney
nephrolith; kidney stone; renal calculus.
##### WordNet
• (Med.), a concretion formed in the excretory passages of the kidney.

#### salivary calculus

• noun a stone formed in the salivary gland
sialolith.

#### Urinary calculus

• noun a calculus formed in the kidney
nephrolith; kidney stone; renal calculus.
##### WordNet
• (Med.), a concretion composed of some one or more crystalline constituents of the urine, liable to be found in any portion of the urinary passages or in the pelvis of the kidney.
