Give an example that meets these expectations Three vectors
Give an example that meets these expectations: Three vectors u1, u2, and u3 in R4 that span the set of all vectors of the form v = (0, v2, v3, v4).
Solution
The vectors u1 = ( 0 , 1 , 0 , 0 ) , u2 =( 0 , 0 , 1 , 0 ) and u3 = ( 0 , 0 , 0 0 , 1 ) spans a set of vectors of the form
( 0 , v2 , v3 , v4 )
For , ( 0 , v2 , v3 , v4 ) =v2 ( 0 , 1 , 0 , 0 ) +v3( 0 , 0 , 1 , 0 ) + v4 ( 0 , 0 , 0 0 , 1 )
= v2u1 + v3u2 + v4u3
