Can one do a bunch of integrals in Mathematica (etc), put the answers in a
table
and use that table for Tilu.

0. I am not a lawyer (IANAL)
1. It seems to be well known that one cannot copyright certain things like
recipes, and
that a particular recipe (eg. an integral) should be reusable without
problem. (IANAL)
2. It could be that there is some other component of intellectual
property embodied in this material, say the ORDER of the integrals, or the
totality
of the collection of the integrals. (IANAL)
3. Translating to another language doesn't seem to be a defense. (IANAL)
4. Why should I take on the legal risk.

IANAL also, but...

Surely there is no serious suggestion that the publishers of a CAS
have any legal claim on results obtained using their software, any more
than the publishers of a word processor have a legal claim on documents
written using it. It would be different if you were publishing the
algorithm used by Mathematica to obtain those integrals.

I was assuming the concern was that Mathematica would object to
this. On closer reading, it seems the problem is not Mathematica
but CRC, if the integrals are the ones from their table. Again
IANAL, but I suppose there may be cause for concern here under
certain circumstances (i.e. for a table of equations where
the left sides are the same as in the CRC table, even if the
right sides are not).
