So, how about that matrix?

**dougdrums** · 02-01-2004 09:32 PM

Code:

&#91;1 4 6&#93; * &#91;5 1 9&#93;

&#91;8 3 3&#93; X &#91;3 2 6&#93;

&#91;9 0 1&#93; * &#91;8 3 3&#93;

so, how about it?

**Kaniaz** · 02-02-2004 02:48 AM

It's a pretty matrix.

that is one amazing matrix

**Stalker** · 02-02-2004 06:50 AM

Now this is a very special matrix:

Code:

&#91;2 3 5&#93; * &#91;1 0 *3&#93;

&#91;2 3 5&#93; x &#91;0 4 -3&#93; = ?

&#91;2 3 5&#93; * &#91;8 6 *9&#93;

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

**Stalker** · 02-02-2004 07:47 AM

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

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

**nerve** · 02-02-2004 08:42 AM

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

**Stalker** · 02-02-2004 08:44 AM

Well linear algebra is fun!

**dougdrums** · 02-02-2004 08:49 AM

heheh...

Code:

&#91;8 3 115&#93;

&#91;8 3 115&#93;

&#91;8 3 115&#93;

ok, now it's right...

I apologize. please continue.

**dougdrums** · 02-02-2004 09:17 AM

quadratic matrix, find the inverse of the x int. (remember the 'or') (did I hear you say wtf?):

Code:

&#91;&#40;9x^2-49&#41; * &#40;3x^2-5x-25&#41; &#40;x^2+7x+12&#41; *&#93;

&#91;&#40;x^2-9&#41; * * &#40;9x^2-18x+9&#41; &#40;x^2+2x+2&#41; * &#93;

&#91;&#40;x^2-5x-14&#41; &#40;x^2-1&#41; * * *&#40;49x^2-14x-3&#41;&#93;

**icedawg** · 02-02-2004 09:17 AM

this seems...SENSELESS TO ME!

**Lowercase Society** · 02-02-2004 09:37 AM

why dont you just buy a calculator...

**dougdrums** · 02-02-2004 09:40 AM

because the calculators that do this cost $100

**dougdrums** · 02-02-2004 09:46 AM

oh, ok...

**Kaniaz** · 02-02-2004 11:51 AM

I have one of those! *finds it*

**Kaniaz** · 02-02-2004 11:54 AM

I entered all the values and it went all funny on me and diplayed

Code:

&#91;49 25 12&#93;

&#91;9 9 2&#93;

&#91;-14 1 -3&#93;

**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

**Kaniaz** · 02-02-2004 01:38 PM

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]

**Artelis** · 02-02-2004 01:38 PM

[A]inverse * [B]

AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

**dougdrums** · 02-02-2004 01:41 PM

well, I solved it, anyone want the answers yet?

**Kaniaz** · 02-02-2004 01:50 PM

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