Expert Solution
Step 1

The given subspace S of the Euclidean inner product space  4 spanned by the vectors ,

v1=1,1,1,1 , v2=1,1,2,4 , v3=1,2 ,-4,-3

(.) Othogonal basis :                                                                   A basis of a subspace S of   of an inner product space is said to  be   orthogonal basis if  ,                                        (u,v) = 0  for all  u,vS such that uv   i.e  inner product of every two distinct   vectors of   is zero .

 where  (u,v) denotes an inner product of   the vectors  u and v .

(.) Inner product :                                                                     Inner product of two vectors  u=(u1,u2,u3,u4) and  v=v1,v2,v3,v4 is given by ,

     (u,v) = u1v1+u2v2+u3v3+u4v4

(.)  A subspace has infinitely many basis . And every basis has same number of vectors .
