[Maxima] Maxima not able to solve an integral, but I think it did before

[Dieter Kaiser]

Hello Robert,

for the integral in your posting I get a noun form with Maxima 5.15.0, 5.16.1,
5.17.0, and 5.18.1 on my Windows system with GCL.

I think nothing has changed.

Betreff: [Maxima] Maxima not able to solve an integral,but I think it did before

Hello, I think I tried the following integral a couple of months ago:

integrate((x^m * (1 - x)^n * (a + b*x + c*x^2))/(1 + x^2), x, 0, 1);

and Maxima was able to find a result, but in 5.18.1, I just get
an integral noun expression.

I seem to recall there was some new code in February which
enabled the solution; was that code disabled or removed or
something is blocking it from working? Or am I just imagining
the whole thing?

Thanks for any info.
