correct, i had intended to include "monic" and somehow skipped it. Edited question.

comment Finding a similarity transform for a matrix that minimizes the (2-norm) condition number
and P is just any matrix of eigenvectors of A? (as per en.wikipedia.org/wiki/Diagonalizable_matrix) I guess this is implied by $AV=V\Lambda \rightarrow V^{-1}AV = \Lambda$ en.wikipedia.org/wiki/…

interesting... are there invertible matrices that are not diagonalizable?

comment Can some clearly explain about lim sup and lim inf?
dumb question: are inf and sup just fancy math names for min and max?

comment Explanation of Chandrupatla's algorithm for root finding?
you're right on the consecutiveness, although I can't quite tell which is which. (I think c is the newest, not positive though)

comment What is Cauchy Schwarz in 8th grade terms?
Vectors are awesome! If you haven't learned them yet, there's a lot to look forward to. (I'm an EE, not a mathematician, use vectors all the time at work.)
