Slightly confused. Would I be correct in saying to find the direction angle of the resultant, I would need to do $\tan^{-1}(\frac y x)$?

Let $f=f(t)=\sum_{i=0}^{4}a_ix^i ,g=g(t)=\sum_{j=0}^{4}b_jx^j \in L[x]$, $L$ is a commutative ring. I would like to compute the resultant of $f$ and $g$. I wish to check a few examples in low dimensions, but even in low dimension (with…
