Linearity - Wikipedia

In mathematics, a linear map or linear function f(x) is a function that satisfies the two properties: • Additivity: f(x + y) = f(x) + f(y). • Homogeneity of degree 1: f(αx) = α f(x) for all α. These properties are known as the superposition principle. In this definition, x … Nettet14. nov. 2013 · Published 14 November 2013.
