A polynomial function is a function that can be defined by evaluating a polynomial. A function f of one argument can be defined as: $$f(x) = \sum_{k=0}^{n} a_k \cdot x^k$$ Polynomial Functions with Python. It's easy to implement polynomial functions in Python. As an example we define the polynomial function given in the introduction of this chapter, i.e. $p(x) = x^4 - 4 \cdot x^2 + 3 \cdot x Solve equation of a type $$p(x; a_1, \ldots, a_k) = q(x)$$ where both $$p$$ and $$q$$ are univariate polynomials that depend on $$k$$ parameters. Explanation The result of this function is a dictionary with symbolic values of those parameters with respect to coefficients in $$q$$ Quadratic equation (2nd-degree polynomial equation) To solve the equation. ax2 + bx + c = 0. input the following Python source. sp.var ( 'x, a, b, c' ) Sol2=sp.solve (a*x** 2 +b*x+c, x) display (Sol2) then you get the answer as its output. x = − b − √b2 − 4ac 2a, x = − b + √b2 − 4ac 2a SymPy's solve () function can be used to solve an equation with two solutions. When an equation has two solutions, SymPy's solve () function outputs a list. The elements in the list are the two solutions. The code section below shows how an equation with two solutions is solved with SymPy's solve () function For something simple, the newton is a pretty good start for simple polynomials, but you can take it from there. For symbolic solutions (which is to say to get y = x**2 -> x = +/- sqrt (y)) SymPy solver gives you roughly what you need. The whole SymPy package is directed at doing symbolic manipulation Sympy is able to solve a large part of polynomial equations, and is also capable of solving multiple equations with respect to multiple variables giving a tuple as second argument. To do this you use the solve () command An alternative to fsolve is root: import numpy as np from scipy.optimize import root def your_funcs (X): x, y = X # all RHS have to be 0 f = [x + y**2 - 4, np.exp (x) + x * y - 3] return f sol = root (your_funcs, [1.0, 1.0]) print (sol.x) This will print. [0.62034452 1.83838393] If you then check from scipy import * x0 = -5 p = poly1d ([1, 1, 1, 1, 1, 1]) # evaluate for x = x0 p (x0) # get roots roots (p) This gives you all roots, including complex ones. If you want only real roots, you can iterate over roots (p) (it's an array) and check that each item's imag attribute is 0.0 Using symbolic math, we can define expressions and equations exactly in terms of symbolic variables. We reviewed how to create a SymPy expression and substitue values and variables into the expression. Then we created to SymPy equation objects and solved two equations for two unknowns using SymPy's solve() function def solve_any_poly(coef): Solving Polynomial The function takes the list of coefficients of the polynomial of any degree and outputs list of all roots of the given polynomial roots=[] for. ### solving polynomial equations using python - ePythonGur 1.
