And again a question:
L is a field for which a \in L . The matrix
A = \frac{1}{2}\left( {\begin{array}{*{20}c}
1 & 1 & 1 & 1 \\
1 & a & { - 1} & { - a} \\
1 & { - 1} & 1 & { - 1} \\
1 & { - a} & { - 1} & a \\
\end{array}} \right)
has the characteristic polynomial
x^4 -...
Hello, I am working on an assignment were I have shown that a certain equation defines an inner product, which was simple enough. Te equation was:
