A linear transformation between topological vector spaces, for example normed spaces, may be continuous. If its domain and codomain are the same, it will then be a continuous linear operator. A linear operator on a normed linear space is continuous if and only if it is bounded, for example, when the domain is finite-dimensional. An infinite-dimensional domain may have discontinuous linear operators.

By the basic properties of differentiations, we have T(f(x) + g(x)) = d dx(f(x) + g(x)) = d dx(f(x)) + d dx(g(x)) = T(f(x)) + T(g(x)). For f(x) ∈ P3 and r ∈ R, we also have T(rf(x)) = d dx(rf(x)) = r d dx(f(x)) = rT(f(x)).

WebThe whole idea behind a derivative is that it's the best linear approximation to the change in a function at a point. That is, the derivative approximates Δf (the change in f) as L (Δx) where L is a linear map. Of course, the best linear approximation to the change in a linear map... is the linear map itself.
