Re: How does Randall do these?

Hi gAr;

Pslq is nice, when it works.


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?

Re: How does Randall do these?

Yes, there was originally one by two guys that I never could get to work.

Re: How does Randall do these?

Which are those?

Re: How does Randall do these?

I do not have the code anymore for them. There is probably later and better code around now. Usually, a CAS has that built in.

Re: How does Randall do these?

Okay, I thought we were talking about some other such integrals.

Did you find the link to the integral okay?

Re: How does Randall do these?

Yes, and I found an analytical solution as well.

Different than the PSLQ got?

You found a method to do it?

Put it as a sum of infinite series.

Would you like to see my solution in that thread?
