compose

$\begin{usage} compose(p)(q) \end{usage}$

$\begin{params} {\em p, q} & \% & Polynomials\\ \end{params}$

$\begin{retval} Returns \begin{displaymath} q(p) = \sum_{i=0}^n a_i p^i \end{displaymath}where $q = \sum_{i=0}^n a_i x^i$. \end{retval}$

$\begin{remarks} If you want to compute $q_1(p),\dots,q_k(p)$\ for several $q_i$... ...the various calls to {\tt f} will share a table of powers of $p$. \end{remarks}$
