Let W be the subspace spanned by u 1 and u 2 . Write y as the sum of a vector in W and a vector orthogonal to W.
Let W be the subspace spanned by u1 and u2. Write y as the sum of a vector in W and a vector orthogonal to W.
Y= [-3] , u1= [1], u2=[-4]
[6] [1] [5]
[5] [1] [-1]
The sum is y=y+z, where y= [ ] is in W and z=[ ] is orthogonal to W. (simplify your answers.)
