scribbled homework, thoughts, quotes and ideas, ripped off and stuffed in my wallet
-- learn trig identities
-- mefies-toi de TROGDOR
-- you've lost all your trig
-- T as in pterodactyl
-- "What is your favorite matrix?" [the linear algebra teacher wouldn't tell us... only his second-favorite]
-- a brief history of time
-- "And now you know why two negatives make a positive" [after an hour-long brief introduction to complex numbers]
-- "I'm like an alternating series"
is quite clearly a math geek

that matrix has no eigen values.

Please conjure up for us a scenario in which a lack of Eigen values is an Eigen value in and of itself.

I wrote a message down on a scrap of paper and dropped it in a box. However it worked out, that piece was handed back to me three hours later.
I left it in my pocket. It says:
'just as it is my destiny to become a shogun.'

number one:
[1 0 1 0]
[0 1 0 1]
[1 0 1 0]
[0 1 0 1]
replacing the 1s by 1/2s
afaik, all matrices have eigenvalues

that's true, i was thinking that last night and i was annoyed at myself and thought about saying something, however i did not. maybe what i meant to say was that the matrix was not diagonalizable. because the eigen values would be
1, -1/2 + i3^(.5)/2, -1/2 - i3^(.5)/2

i'd disagree with that too, aksually - it is diagonalizable (not deficient, 3 eigenvalues), it's just that the diagonal matrix is a tad imaginary
but i could be wrong o.O

oh man i don't know. i see how it perhaps could be diagonalizable, but i don't know how to do it.
i had a slip of paper that told me to learn trig identities too, i still haven't done it yet.

they say to carry two slips of paper in your pocket- the first reads, "for me the entire world was created," the second, "I am but dust and ashes."
