if $$u = (\frac{ 1 }{ \sqrt{5} },(\frac{ -1 }{ \sqrt{5} }) ,v=(\frac{ 2 }{ \sqrt{30} },(\frac{ 2 }{ \sqrt{30} })$$ show that {u,v} is orthonormal if $$IR^2$$ has inner product $$<u,v> = 3u_1v_1+2u_2v_2$$ but not orthonormal if $$IR^2$$ has the euclidean inner product

anonymous · Answer

so boring to type this all

anonymous · Answer

haha well instead of typing it , can u take a snap ?

anonymous · Answer

-.-
i think thats a very nice idea

anonymous · Answer

so do you know how to solve it? @BSwan  @dan815

anonymous · Answer

well , its direct 
just apply the  given inner product  
whats ur course name ?

dan815 · Answer

yah

dan815 · Answer

dot product is just x1x2+y1y2

dan815 · Answer

for euclidian

anonymous · Answer

computer science
n it has maths in it
-.-

anonymous · Answer

the course name CS ?
weird hehe

anonymous · Answer

oh you both know the answer,give each other a medal
i am graduating in computer science

ganeshie8 · Answer

whats $IR^2$ ?

anonymous · Answer

lol i dnt care for medal or answer 
i gave u a hint why dnt u try to solve :D

anonymous · Answer

IR as in real number @ganeshie8 and IR^2 as in 2 dimensional

anonymous · Answer

@BSwan  yeah i will solve it,seems like it was easy afterall

anonymous · Answer

IR^2
I : identity
(0,0) for addition
(1,0) , (0,1) for multiplication
R^2 domain ( R *R )
means both x,y in u and v are real

ganeshie8 · Answer

lol okie :)  this one  $\large \mathbb R$

anonymous · Answer

yeah for n dimention :-
its IR^n
