NumberTheory`Recognize`

This package defines the function Recognize for determining a polynomial with integer coefficients, given an approximate real zero of the polynomial and the degree of the polynomial. The resulting polynomial is normally not unique.

In[1]:=

This finds a linear polynomial in t with solution 1.7.

In[2]:=

Out[2]=

NSolve gives the numerical solutions of a cubic equation.

In[3]:=

Out[3]=

Here is the first solution.

In[4]:=

Out[4]=

This result is proportional to the original polynomial used in NSolve.

In[5]:=

Out[5]=

Here is a quadratic polynomial for which sol is an approximate solution.

In[6]:=

Out[6]=

This result is a polynomial of degree 5.

In[7]:=

Out[7]=

If the penalty is large enough, a lower-order polynomial may be returned.

In[8]:=
