"This is what f'(c) = 0 means, as f' is a common notation for the derivative of the function f in differential calculus." Is it? I took both calculus and differential equations as an undergraduate (in the United States in the 1970s/1980s) and never saw that notation.[[User:Nitpicking|Nitpicking]] ([[User talk:Nitpicking|talk]]) 17:57, 1 August 2022 (UTC) | "This is what f'(c) = 0 means, as f' is a common notation for the derivative of the function f in differential calculus."

Not really much experience the '70s, but definitely across the early '80s and beyond. For Secondary Education, in the first instance. Not sure what system dominated beyond secondary and tertiary/college levels and into my own university years (heading towards the '90s). It might have depended on whether it was the physics or the maths lectures and workshops (or indeed the given lecturer/workshopper of the moment) as to which of the many possible conventions we could have used and be considered correct. dFoo/dBar probably was used a lot, but obviously got messier than ''f''unctioning things when going far into that sort of thing (either direction!) |
:I went a-looking and it ''is'' fairly common, even unto {{w|Derivative#Higher_derivatives|higher derivatives with multiple marks}} (which I've used, well... to no more than the third degree, probably). | :I went a-looking and it ''is'' fairly common, even unto {{w|Derivative#Higher_derivatives|higher derivatives with multiple marks}} (which I've used, well... to no more than the third degree, probably). | ||
:Looking further still, I now know (have reminded myself?) that {{w|Notation for differentiation#Lagrange's notation|it's 'Lagrangian' notation}}, at least as far as it stays unawkward before going into the numeric form rather than repeated Prime-marks towards a sublime ridiculousness. | :Looking further still, I now know (have reminded myself?) that {{w|Notation for differentiation#Lagrange's notation|it's 'Lagrangian' notation}}, at least as far as it stays unawkward before going into the numeric form rather than repeated Prime-marks towards a sublime ridiculousness. | ||
:Of course, elsewhere on that latter link you might find your own learnt system. Or various others more familiar to you and which I ''may'' as readily recognise, unprompted.
