This is also how one gets around the lack of chainrule in Pearson Blue Book 1, not that it mentions it. It gives the reason that e^kx goes to ke^kx under differentiation without having to use my "magic maths hands".

#AutoDiff
A meme following the "They have played us for absolute fools" format. It reads: " STOP DOING AUTODIFF COMPUTER PROGRAMS WERE NOT TO BE DIFFERENTIATED! HUNDREDS OF AD SYSTEMS and yet NO REAL-WORLD USE FOUND for anything more than applying the CHAINRULE on derivative functions written BY HAND. Want to differentiate arbitary functions anyway for a laugh? We had a tool for that it was called FINITE DIFFERENCING! "The pullback is product of the jacobian transpose with the sensitivity" — statements dreamed up by the utterly deranged. (This is REAL AD, used in REAL AD systems) " Then are shown two pictures. A category theory optic diagram labelled "?BINOCULARS?". and a line-graph showing subderivatives labelled "LINEY-BOY" The text then concludes: " `gradient(x->println("$x apples"), 3)` They have played us for absolute fools "

I think if they can spot reverse chainrule for

1/(xlnx)

then they have earned the right to choose their own path 🤣🤣🤣

Reskeet with favourite meme you have created.

(Rare: me talking about my day job on bluesky)
