A "How to" describes how to carry out particular tasks with Mathematica, giving step-by-step instructions for common cases.
Mathematica notebooks consist of sequences of cells, which can be nested. The hierarchy of cells serves as a structure for organizing information in a notebook as well as ...
The default behavior for a function in Mathematica is carefully chosen to be suitable for the vast majority of cases. Mathematica also gives you fine-grained control over the ...

Accuracy[x] gives the effective number of digits to the right of the decimal point in the number x.
f' represents the derivative of a function f of one argument. Derivative[n_1, n_2, ...][f] is the general form, representing a function obtained from f by differentiating n_1 ...
DirichletL[k, j, s] gives the Dirichlet L-function L(\[Chi], s) for the Dirichlet character \[Chi](n) with modulus k and index j.
DivisorSum[n, form] represents the sum of form[i] for all i that divide n.DivisorSum[n, form, cond] includes only those divisors for which cond[i] gives True.
