2019-09-08 17:21:17 +0200 | asked a question | How to evaluate polynomial in a polynomial ring at a particular value Apologies in advance if this question is too simple. I have the following situation: I have a vector space over a polynomial ring, and at some point in my program I need to sub in a value for the indeterminate $t$, and evaluate the polynomial. The set up is as follows: Then for example I have the vector: I simply want to evaluate $2*t$ at $t = sqrt(2)$ as a function from $\mathbb{R}$ to $\mathbb{R}$. What is the easiest way to go about this? |
