[1 4 6] * [5 1 9]
[8 3 3] X [3 2 6]
[9 0 1] * [8 3 3]
so, how about it?

It's a pretty matrix.

that is one amazing matrix

Now this is a very special matrix:
[2 3 5] * [1 0 *3]
[2 3 5] x [0 4 -3] = ?
[2 3 5] * [8 6 *9]

[|= |_| ( |< ]
[|/| 4 7 |2 1 x]
[7 |-| |2 3 4 |) 5. ]

[quote][|= |_| ( |< ]

Now that wasn't very nice. What's wrong with a little mathematics?

um. the fact that I see like 5 new matrix threads every week?

Well linear algebra is fun!

heheh...
[8 3 115]
[8 3 115]
[8 3 115]
ok, now it's right...

quadratic matrix, find the inverse of the x int. (remember the 'or') (did I hear you say wtf?):
[(9x^2-49) * (3x^2-5x-25) (x^2+7x+12) *]
[(x^2-9) * * (9x^2-18x+9) (x^2+2x+2) * ]
[(x^2-5x-14) (x^2-1) * * *(49x^2-14x-3)]

why dont you just buy a calculator...
dougdrums
02-02-2004, 09:40 AM
because the calculators that do this cost $100

I entered all the values and it went all funny on me and diplayed
[49 25 12]
[9 9 2]
[-14 1 -3]
dougdrums
02-02-2004, 01:13 PM
you have to find what x equals first, and then find the inverse... that TI-92 plus isn't going to help you here!
Kaniaz
02-02-2004, 01:14 PM
You're wrong.
It's not a TI 92.
dougdrums
02-02-2004, 01:21 PM
well, anything under and including the ti-92 pluss won't help. (Well, maybe a little, but you can't solve it completly with one

I'll just get some university professor to solve it for me.
Me: Solve this matrix for me.
Professor (thinking): Well, he's obviously a dumb lunatic, so I'll get rid of him easily.
Professor: The quadrant of pi times x to the third is 3.147.
Me: AH! INTELLIGENCE! IT BURNS![/b]

Why the heck are we talking about this boring stuff anyway?

ok, I'm giving you the answers anyways:
[1/76 * * *-13/228 * * *7/57 * * *]
[13/114 * -56/171 * * *-35/342 ]
[-35/228 *-343/684 * * -91/342]

Can't anyone solve this? It's not difficult but the answer is interesting.

Am I missing something here or is something missing? That's just a bunch of expressions but they don't equal anything so how are you supposed to solve for x? If something is missing then I can probably solve it with Maple.
