Comment #3 on issue 4133 by gre...@gmail.com: Suggestion: implement
classical orthogonal polynomials
http://code.google.com/p/sympy/issues/detail?id=4133
Maybe this is a different issue, but it seems like it would be good to keep
the representation as a known orthogonal polynomial (which are evaluated
stably) type instead of reverting to monomials (is Horner being used
here?). I find that when I evaluate a reasonably high order Chebyshev
polynomial on a grid with lambdify, the results are disastrous. Perhaps I
am doing something foolish here though.
