Step 3

Find the orthogonal basis by Gram Schmidt Orthogonalisation process.

Let (1-1,0,1,1
v= (3,-3,2,5,5)
be the orthogonal basis. Then by Gram Schmidt's process
Let Wi and W
(1,-1,0,1,1)
-Wi
(Mi.Wa
((3,-3,2,5,5).(1.-1,0,1,1)
(1-1,0,1,1),(1-1,0,1,1)
(3,-3,2,5,5)
-(3,-3,2,5,5)-4(1-1,0,1,1)
= (-1,1,2,1,1)
Hence,1,-1,0,1,1),(-1,1,2,1,1)} is the orthogonal basis.
