comment Show using Riemann sum that error approximation is bounded above by $\frac{7}{n}$
Try to do the case $n = 1$ and $n = 2$ first.

comment Prove that $f(x)$ is irreducible iff its reciprocal polynomial $f^*(x)$ is irreducible.
It is enough to assume that $f(0) \neq 0$ and $\deg f > 1$ to have $\left( f^{*} \right)^{*} = f$ and so with some careful modifications, it seems that the proof does go through. Thanks for the correction!

comment Determining a basis for the subspace of T(2,2) consisting of transformations such that T(v) = 0 for a specific vector v
You still obtain a basis. Try this with $\mathbf{v} = (0,1)$.

Yes - if the vector $\mathbf{v}$ is not given to you explicitly, the best you can get is to express the basis for $S$ in terms of the coordinates of $\mathbf{v}$ (which are not known) like you did.
