Calculus (disambiguation)

Calculus (Latin for pebble, pl. calculi) in its most general sense is any method or system of calculation.

Calculus may refer to:

In mathematics and computer science

• Calculus, also "the calculus", short for "differential calculus" and "integral calculus", which investigate motion and rates of change
• Logical calculus, a formal system that defines a language and rules to derive an expression from premises.
• Precalculus, a family of mathematical topics that prepare students to begin to study differential and integral calculus
• The calculus of sums and differences (difference operator), also called the finite-difference calculus, a discrete analogue of "the calculus"
• In symbolic logic:
  • the propositional calculus, specifies the rules of inference governing the logic of propositions
  • the predicate calculus, specifies the rules of inference governing the logic of predicates
  • a proof calculus, a framework for expressing systems of logical inference
  • the sequent calculus, a proof calculus for first-order logic
• Bondi k-calculus, a method used in relativity theory
• Domain relational calculus, a calculus for the relational data model
• Epsilon calculus, a logical language which replaces quantifiers with the epsilon operator
• Functional calculus, a way to apply various types of functions to operators
• 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
• Matrix calculus, a specialized notation for multivariable calculus over spaces of matrices
• Modal μ-calculus, a common temporal logic used by formal verification methods such as model checking
• Non-standard calculus, an approach to infinitesimal calculus using Robinson's infinitesimals
• 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
• Umbral calculus, the combinatorics of certain operations on polynomials
• The calculus of variations, a field of study that deals with extremizing functionals
• Vector calculus (also called vector analysis), comprising specialized notations for multivariable analysis of vectors in an inner-product space
