2578 [with patch, positive review] make bernoulli_polynomial independent of maxima was craigcitro "
I wanted to verify that Sage could symbolically compute the derivative
of Bn(x), the nth Bernoulli polynomial in (x): Dx[Bn(x)]=n*Bn-1(x).
The following code causes Sage to lockup:
{{{
Bn = bernoulli_polynomial(x,n)
}}}
The command ""bernpoly(x,n)"" in Maxima does not lock up but Maxima
will not compute symbolically.
{{{
sage: B3 = bernoulli_polynomial(x,3)
sage: B4 = bernoulli_polynomial(x,4)
sage: DxB4 = diff(B4,x)
sage: print expand(DxB4-4*B3)
0
sage: Bn = bernoulli_polynomial(x,n)
Traceback (most recent call last):
...
KeyboardInterrupt
