Derivative as a linear map

WebThe differential is another name for the Jacobian matrix of partial derivatives of a function from Rn to Rm (especially when this matrix is viewed as a linear map ). More generally, the differential or pushforward refers to the derivative of a map between smooth manifolds and the pushforward operations it defines. WebJun 5, 2024 · Finding the differential or, in other words, the principal linear part (of increment) of the mapping. The finding of the differential, i.e. the approximation of the mapping in a neighbourhood of some point by linear mappings, is a highly important operation in differential calculus.
