ExpIntegralE[n, z] gives the exponential integral function E_n (z).

LerchPhi[z, s, a] gives the Lerch transcendent \[CapitalPhi] (z, s, a).

When you make a definition in the form f[args]=rhs or f[args]:=rhs, Mathematica associates your definition with the object f. This means, for example, that such definitions ...

Although Mathematica matches patterns in a purely structural fashion, its notion of structural equivalence is quite sophisticated. In particular, it takes account of ...

The numerical method of lines is a technique for solving partial differential equations by discretizing in all but one dimension, and then integrating the semi-discrete ...
