1: 27.20 Methods of Computation: Other Number-Theoretic Functions
A recursion formula obtained by differentiating (27.14.18) can be used to calculate Ramanujan’s function τ ( n ) , and the values can be checked by the congruence (27.14.20). …

and follows from the differentiated form of (3.3.4). …
§3.4(ii) Analytic Functions
3: 2.1 Definitions and Elementary Properties
§2.1(ii) Integration and Differentiation
Differentiation requires extra conditions. …This result also holds with both O ’s replaced by o ’s. … means that for each n , the difference between f ( x ) and the n th partial sum on the right-hand side is O ( ( x - c ) n ) as x c in X . … Differentiation, however, requires the kind of extra conditions needed for the O symbol (§2.1(ii)). …

§1.8(iii) Integration and Differentiation
If a function f ( x ) C 2 [ 0 , 2 π ] is periodic, with period 2 π , then the series obtained by differentiating the Fourier series for f ( x ) term by term converges at every point to f ( x ) . …
