Differentiation rules - Wikipedia
https://en.wikipedia.org/wiki/Differentiation_rulesUnless otherwise stated, all functions are functions of real numbers (R) that return real values; although more generally, the formulae below apply wherever they are well defined — including the case of complex numbers (C). For any functions and and any real numbers and , the derivative of the function with respect to is In Leibniz's notation this is written as:
