Hi, I mentioned this before in the context of the Sine Integral, Si(x), but it appears that neither Sage nor Maxima have support for the Sine Integral, Si(x) or the Cosine Integral, Ci(x).
See, http://mathworld.wolfram.com/SineIntegral.html and http://mathworld.wolfram.com/CosineIntegral.html I'd expect that if I put one of the integrals to be integrated, I'd get the function back. That's what FriCAS does, but Sage doesn't recognize the function. I think Maxima supports the integral as a definite integral, but I think the functions should be there like the various other special function integrals. Thoughts?
