# Calculus (disambiguation)

Calculus (from Latin calculus meaning ‘pebble’, plural calculī) in its most general sense is any method or system of calculation.

Calculus may refer to:

## Mathematics

• Calculus, short for "differential calculus" and "integral calculus", which investigate motion and rates of change
• Calculus of sums and differences (difference operator), also called the finite-difference calculus, a discrete analogue of "calculus"
• Functional calculus, a way to apply various types of functions to operators
• Non-standard calculus, an approach to infinitesimal calculus using Robinson's infinitesimals
• Schubert calculus, a branch of algebraic geometry
• Tensor calculus (also called tensor analysis), a generalization of vector calculus that encompasses tensor fields
• Vector calculus (also called vector analysis), comprising specialized notations for multivariable analysis of vectors in an inner-product space
• Matrix calculus, a specialized notation for multivariable calculus over spaces of matrices
• Umbral calculus, the combinatorics of certain operations on polynomials
• The calculus of variations, a field of study that deals with extremizing functionals
• AP Calculus

## Logic

• Logical calculus, a formal system that defines a language and rules to derive an expression from premises.
• Calculus of relations, manipulation of binary relations with the algebra of sets, composition of relations, and transpose relations
• Epsilon calculus, a logical language which replaces quantifiers with the epsilon operator
• Fitch-style calculus, a method for constructing formal proofs used in first-order logic
• Modal μ-calculus, a common temporal logic used by formal verification methods such as model checking

## Computer science

• Domain relational calculus, a calculus for the relational data model
• Join calculus, a theoretical model for distributed programming
• Lambda calculus, a formulation of the theory of reflexive functions that has deep connections to computational theory
• Pi-calculus, a formulation of the theory of concurrent, communicating processes that was invented by Robin Milner
• Refinement calculus, a way of refining models of programs into efficient programs
• Rho calculus, introduced as a general means to uniformly integrate rewriting and lambda calculus
• Tuple calculus, a calculus for the relational data model, inspired the SQL language
