The Derivative and Higher Derivatives

2007
The derivative of a function, even if it exist everywhere, can be discontinuous. For example, if \(f\left( x \right) = {x^2}\sin \frac{1}{x}\), for x ≠ 0, f(0) = 0, then for x ≠ 0, \(f'\left( x \right) = - \cos \frac{1}{x} + 2x\sin \frac{1}{x}\), which does not tend to any limit as x tends to 0, although f′(0) exists and equals 0, as may be easily ...

Derivability

Reports Math. Log., 1999
Man betrachtet die Ableitbarkeit im klassischen Prädikatenkalkül durch irgendein \(\langle R,X\rangle\), wobei \(X\) eine Menge von Formeln ist, die als Axiome betrachtet werden, und \(R\) eine Menge von Ableitungsregeln ist. Bei fixierten \(\langle R,X\rangle\) soll für eine beliebige Regelmenge \(r\) der Ausdruck \(r\in\text{Der}(R,X)\) bedeuten ...

Derivation of the third-order directional derivative

Pattern Recognition Letters, 1993
Summary: We give an easy derivation of the third order directional derivative in the direction of the gradient of the intensity function. The obtained formula is a correction of the formula found by \textit{J. J. Clark} [IEEE Trans. Pattern Anal. Mach. Intell. 11, No. 1, 43-57 (1989; Zbl 0665.68066)].

[Electrocardiograms: derived derivations!]

Revue de l'infirmiere, 2018
Simple and non-invasive, the electrocardiogram is a basic examination for studying how the cardiac muscle functions. Very commonly used, it nonetheless requires great rigour when applying the electrodes to avoid false results that can be harmful to appropriate care for the patient. A reminder of good practices.
