http://www.mitrikitti.fi/multivariatecalculus.pdf 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.

WebThe differential of a one-dimensional function x ↦ f ( x) is the linear map d f x: v ↦ f ′ ( x) v (well, family of linear maps). Thus, in your case, f ′ ( x) = 1 implies the differential is v ↦ v, which is in fact the same as f, namely the identity map. – anon May 15, 2013 at 7:59 … We would like to show you a description here but the site won’t allow us.
