I have a problem (context: trying to find radius of convergence of a Taylor series related to Newton's method). Sage throws a bizarre exception without any useful information. Changing from `QQbar…

After #25162, it seems that the content of `partition_algebra.py` is no longer needed, but when looking for partition algebras, one may be misled that this is what's implemented (also because of htt…

Some trivial substitutions are not done by solve:
```
sage: x,y=var('x,y')
sage: solve([y==exp(x),2*y-exp(x)==1],x,y)
[y == e^x, 2*y - e^x == 1]
```
and, as reported in http://ask.sagemath.org/ques…

See [this ask.sagemath question](http://ask.sagemath.org/question/24532/). Original report is

sage: F = sqrt((cos(x) - 1)^2 + sin(x)^2)
sage: F.integrate(x, 0, 2*pi)
0

In SageMath 9.4.beta3, the rank of `B` changes from 0 to 3 in the following example:
```
sage: M = ModularSymbols(Gamma0(4), 4)
sage: B = M.boundary_space
sage: B.rank()
0
sage: M.boundary_map()

Currently, the documentation for orthogonal polynomials is not very user-friendly (see https://doc.sagemath.org/html/en/reference/functions/sage/functions/orthogonal_polys.html).
Some functions mis…
