Find ||u|| if u=[1,1,0]

Question

anonymous · Answer

Also, what does ||u|| mean?

anonymous · Answer

(1+1)^1/2=sqrt(2)

anonymous · Answer

are you trying to find the magnitude?

anonymous · Answer

Sorry, $$u=\left(\begin{matrix}1\1 \ 0\end{matrix}\right)$$Not sure if that makes a difference...

Answer says sqrt(3)...

anonymous · Answer

Erm I'm using it as part of the Gram-Schmidt process, but can't figure out how it ends up being sqrt3...

anonymous · Answer

hey man are u trying to find the square root or unit vectors?

anonymous · Answer

i meant the magnitude*

anonymous · Answer

Dunno - using it as part of $$v_1 = u_1/||u_1||$$Where$$u_1 = \left(\begin{matrix}1\1 \ 0\end{matrix}\right)$$The answer for this step shows $$\left(\begin{matrix}1\1 \ 0\end{matrix}\right)/\sqrt{1+2+0}$$

anonymous · Answer

what does the double bar stand for have any idea?

anonymous · Answer

does it mean magnitude or something else?

anonymous · Answer

$$=\left(\begin{matrix}{1/{\sqrt{3}}}\{1/{\sqrt{3}}} \ 0\end{matrix}\right)$$

anonymous · Answer

I think it is magnitude or norm

anonymous · Answer

pellet never mind - I got it! Didn't see we are given the inner product relation... Cheers anyway bro!

anonymous · Answer

something is fishy about ur problem

anonymous · Answer

(hahaha "s***" automatically changes to "pallet")

anonymous · Answer

oh ok this is for linear algebra right?

anonymous · Answer

Yeah
