If I have a polynomial, for example in three variables such as x, y, and z. How do I generate a polynomial that is a select subset of the powers of x, y, and z in the original polynomial? For example if x, y, and z are small compared to one I would like a polynomial that only consists of the zero and first order terms of x, y, and z of the original polynomial.
f(x,y,z) = a0+a1*x+a2*y+a3*z+a12*x*y+a23*y*z+a31*z*x+a123*x*y*z return g(x,y,z) = a0+a1*x+a2*y+a3*z --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
