Thanks, please elaborate on the transformation...

Hi Jhevon and JakeD,

it is always perfect with quick replies...

Yes, Jhevon, they are separate - I tried to make a few spaces, but I guess they were removed, when I posted. : o )

JakeD, I see your solution, and it is right, but...

How is it you find the matrix? I see how it works, how you multiply the matrix with the information in T(e(1)+e(2)) as seen in your post - the first math-input...

Suppose, you're looking at the first case... What I don't get is? Why don't you just choose a matrix of pure 1/2? That would be satisfying...

I guess what I am asking is - how do set up and equation, so you get the condition from the other information too - and end up with your matrix..?

Did that make any sense?

Hi Jhevon and JakeD, thanks.

Thanks for your replies! :)

It was a big help. I think, I'd be able to solve a similar assignment, if it is part of the exam, which I'm taking tomorrow.

It makes a little more sense now too, because I've been working on other topics in linear algebra for the last days, so it is all coming together - just not fast enough to ace the test tomorrow, but - maybe next time, for now - I'm just looking to pass.

Have a nice day,

Simon DK.
