I got this error:
```
julia> Pl(1.2,3)
DomainError with 1.2:
Legendre Polynomials are defined for arguments lying in -1 ⩽ x ⩽ 1
```
I am somewhat perplexed. A polynomial defined on -1 ⩽ x ⩽ …

Hello,
I am constructing the Lagrange Polynomials using lagrange_polynomial function in chaospy and have a problem. I have 5 sampling points, the problem is 2D.
I am writing as:
Lagrange = cp.l…

I'm logging this here as this seems to be a mpmath problem. The polynomial
'f' defined below is of order 2, and so it does not contain the 3rd

It would be very convenient if Oscar had a method to find the roots of a multivariate polynomial over a finite field.

the lattice of finite fields identifies fields by degree - which cannot work if the fields have user chosen defining polynomials. We might (will have!) mutiple fields with the same degree (and same ch…

This ticket aims at improving the method `valuation` for polynomials in two ways:
1. The method `valuation` for dense polynomials can be called in the following ways:

Boolean polynomials lack a `dict` method
available for other polynomials.
This prevents expressing a multivariate polynomial
as a polynomial in one if its variables.
Define a boolean polynomial:

As a side effect substitution and addition is also broken:
