Higher order models wiggle more than do lower order models. solve(expression) method, we can solve the mathematical equations easily and it will return the roots of the equation that is provided as parameter using sympy. If you know the roots of a polynomial, its degree and one point that the polynomial goes through You use numpy (apparently), but I've never tried it myself though: # Python program for solving a quadratic equation. If we find one root, we can then reduce the polynomial by one degree (example later) and this may be enough to solve the whole polynomial. The coefficients and the evaluation point may be any combination of real or complex numbers. If x = 2, then ( x - 2) is a factor of the polynomial. 4531004 j 0.
