For integers n, with n > -1, it should be the case that
assoc_legendre_p(n,0,x) - legendre_p(n,x),
assoc_legendre_q(n,0,x) - legendre_q(n,x).
So, yes for assoc_legendre_p(a,b,x) and assoc_legendre_p(a,b,x),
the first argument is what I would call the degree, and
the second is the order. My macsyma uses the same
convention.

I'll try to improve it.
