    Does anyone know of a nice calculator for calculating the real and complex parts of a complex polynomial. Say, for example, I want to write the polynomial $p(z)=z^3+2z^2+1$ as a function $f(x,y)=(f_1(x,y),f_2(x,y))$, but I do not want to calculate $f_1$ and $f_2$ by hand.

      You can just use the binomial theorem to separate real and imaginary parts.

    Or write it this way.

    Thanks, I have almost no experience with doing math on computers, so that was very helpful.
