Thread: Solve U=(I+S)(I-S)^(-1)

Sorry to bother you all, but I don´t know anywhere else to turn!!!

(think I posted it in the wrong section before)

I´m new here, but my ex is trying to put me into trouble, and I need you help!!!

Can´t give you the exact details right now but the problem is that he is threatening me with that I can' t solve this!!

Could you please help me out??

The question I have to answer:

He says, solve this:

U=(I+S)(I-S)^(-1)

S is not symmetric,

I is identity matris,

then U is ortogonal.

PLEASE HELP ME OUT!!

I´ll give you a great hug!!! or a

Do you know the definition of a symmetric matrix?

Sorry!!!! But I don´t really know?

Are you that one who can help me out anyway?

I would really appriciate it you know........

If you don't know what a symmetric matrix is, why are you insisting on doing this problem?

Do you know what an orthogonal matrix is?

I am sorry!

But it´s my ex who is trying to make me look stupid.

This is hard for me, can you give me an answer to give him?

The fact that you know or don't know linear algebra doesn't imply that you are stupid. If you haven't taking the course, you wouldn't be expected to know the material then.

Your post asks for help but in fact you just want an answer.

Even if you are provided with the answer, do you think you are going to have the ability to explain it?

You shouldn't care what someone thinks when they are acting in a childish way.

Yes, i would understand it. I have a National exam in physics, but he´s trying me on this one..

So can you answer it or not ???? I don´t get you???

You were already explained that if you don't know any linear algebra then you shouldn't be trying to do this question: it just doesn't make any sense.

And nobody get's very worried about your saying about your ex threatening or whatever. One thing I can tell you: if he's really trying to make you look stupid then you probably shoud begin to ponder kick him away.

Ps. By the way, the claim is false, if you're interested.
