Function maps to 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. Thanks anon, that makes sense.

WebIt is called an identity function because the image of an element in the domain is identical to the output in the range. Thus, an identity function maps each real number to itself. The output of an identity function is the same as its input. Identity functions can be identified easily as the pre-image and the image are identical. WebOct 8, 2015 · 1 Answer. Sorted by: 1.
