comment How to reach this result using only matrix operations?
@lynn Where did $\mu_w$ come from? Do you mean $\lambda_{\mu}$? Would appreciate it if you could explain in a little more detail how you reached this solution. Might even accept it as an answer.

comment Is it possible to solve for scalar in this multiplication of two quadratic forms involving inverse matrix?
But $\lambda$ is in $a^2$.

comment What does it mean for a number to be “larger” than another number?
So here you have introduced a point of reference--0--with respect to which "farther" is measured. It might be argued that the issue of "size" is different in that no such point of reference is required.
