A derivative or differentiated function: in Lagrange's notation, f ′ (x) and f ″(x) are the first and second derivatives of f (x) with respect to x. Likewise are f ‴(x) and f ⁗(x). Similarly, if y = f (x), then y ′ and y″ are the first and second derivatives of y with respect to x. Other notation for derivatives also exists (see ...
