Thanks for your suggestions. I'm still pretty confused as to what exactly this problem wants me to find, but this definitely gives me some place to start.
Let me see if I'm interpreting that correctly. That would involve solving a system of linear equations involving the columns of A and the components of the vector v. Then would I use that vector to compute the distance in terms of the inner product space? I'm a little unclear what b is in that...
I meant to say that the matrix in question has orthogonal columns (which is mentioned in the problem). I overlooked the fact that an orthogonal matrix is something completely different.
Homework Statement
A problem on a linear algebra assignment is really confusing me. The problem is asking me to compute the distance from a vector to the image of a matrix (with orthogonal columns).
matrix A =
1 -2
4 6
2 -11
y=
3
-5
2
