Homework Statement
The Attempt at a Solution
For part ii) I wrote it out as a matrix, getting
\begin{array}{ccccccc}
0 & 0 & 0 & 0 & ... & 0 \\
0 & 0 & 2 & 0 & ... & 0 \\
0 & 0 & 0 & 6 & ... & 0 \\
. & . & . & . & . & . \\
0 & 0 & 0 & 0 & ... & N(N-2) \end{array}
So the rank = N-2 and the nullity = 2
However for part i) I'm not entirely sure how to go about it. Is it enough to show the map can be written as a matrix form, or do I need to show the additivity and scalar multiplication things hold over differentiation? Or is either ok?
Cheers.
