WebSep 2, 2024 · Linear functions; Matrix Notation; Affine functions; One of the central themes of calculus is the approximation of nonlinear functions by linear functions, with … Given two affine spaces A and B whose associated vector spaces are and , an affine map or affine homomorphism from A to B is a map such that is a well defined linear map. By being well defined is meant that b – a = d – c implies f(b) – f(a) = f(d) – f(c).
