Differential may refer to: ==Mathematics== * Differential (mathematics) comprises multiple related meanings of the word, both in calculus and differential geometry, such as an infinitesimal change in the value of a function * Differential algebra * Differential calculus * * Differential of a function, represents a change in the linearization of a function * * * Total differential is its generalization for functions of multiple variables * * Differential (infinitesimal) (e.g. ''dx'', ''dy'', ''dt'' etc.) are interpreted as infinitesimals * * Differential topology, in multivariable calculus, the differential of a smooth map between Euclidean spaces or differentiable manifolds is the approximating linear map between the tangent spaces, called pushforward (differential) * Differential exponent, an exponent in the factorisation of the different ideal * Differential geometry, exterior differential, or exterior derivative, is a generalization to differential forms of the notion of differential of a function on a differentiable manifold * Differential (coboundary), in homological algebra and algebraic topology, one of the maps of a cochain complex * Differential cryptanalysis, a pair consisting of the difference, usually computed by XOR, between two plaintexts, and the difference of the corresponding ciphertexts 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「differential」の詳細全文を読む スポンサード リンク
