What about renaming `derivemxE` to `deriveEjacobian` ? https://github.com/math-comp/analysis/blob/14c5bf819bce88100955bc655f0307568e13391c/theories/derive.v#L356 In my opinion, it is more appropriate because we can see by the name which alternative definition of directional derivative we're about...
##### Motivation for this change When deriving differential equations using lsubmx/rsubmx, we need proofs of their differentiability. This PR also contains a lemma making use of the "is_derive1_sqrt" lemma to...
