Tough linear algebra problem

Let u = (1-i  1+i)
this is meant to be written as one colum and two rows of course.
Find the absolute value of u.

If that's too easy then if V= (1 z) is orthogonal to u, find the complex number z.

gahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!!!!!

Re: Tough linear algebra problem

Hi mrpace;

If that's too easy then if V= (1 z) is orthogonal to u, find the complex number z.

Solving for z we get z = i

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
