You might be interested in the online version of the Handbook of
Mathematical functions from NIST. It is available at
http://dlmf.nist.gov/.


You can download a formula to Mathematica by Importing in LaTeX or
MathML from the URL provided with a formula. For example:

A generating function for the Chebyshev polynomial of the first kind may
be found at http://dlmf.nist.gov/18.12, equation 7 and downloaded using
any of the three following.

LaTeX --
Import["http://dlmf.nist.gov/18.12.E7.tex","NotebookObject"]
The LaTeX option brings up a notebook displaying the function --
but it generally requires some editing to convert it into valid
Mathematica input syntax.

MathML --
Import["http://dlmf.nist.gov/18.12.E7.pMML","MathML"]
I have not been able to do anything useful with the MathML input.

If you only want a picture --
Import["http://dlmf.nist.gov/18.12.E7.png"]

And the fragility spreads. It's a little depressing that two projects
with a similar subset of goals can't simply interoperate. And that
with, what, 14 yrs behind DLMF and > 20 behind Mathematica.

Nonetheless, Abramowitz and Stegun probably needed an update.

Which has nothing to do with my preference for the Wolfram Functions
site.
