- I suggest a function with the following semantics:
* call *RealRootsSmallValue(f, eps)*
* result is a list of close... - 14:19 Bug #1171: RealRoots: first point is sometimes wrong?
- It is not as simple as I first thought. While the first order approximation I mentioned in comment 3 is correct, it ...

- which package?
- 09:30 Bug #1172 (Closed): MinSubsetOfGens: problem with generators = 0
- In case of type MODULE there is:
J := submodule(ModuleOf(X), WithoutNth(L,I));
but it does not allow to v... - 11:34 Bug #1171 (In Progress): RealRoots: first point is sometimes wrong?
- One can estimate the "stability" of the root by computing the value of the derivative at that root. By Taylor expans...

- I found this bug while debugging @ApproxSolve@.
I had noticed that, when the answer was wrong, it was just on the fi... - 18:25 Bug #1171 (Closed): RealRoots: first point is sometimes wrong?
