Question: Let V = (a) Suppose a vector 1 3 2 = X1 X2 4683 X 3 X4 0 and V3 = D is orthogonal

Let V = (a) Suppose a vector 1 3 2 = X1

Let V = (a) Suppose a vector 1 3 2 = X1 X2 4683 X 3 X4 0 and V3 = D is orthogonal to all three vectors V, V2 and v3. Write down a system of linear equations satisfied by the components x1, x2, x3, x4. (b) Find a unit vector in R4 that is orthogonal to all three vectors V, V2, and v3. (c) Construct a 2 x 4 matrix whose nullspace is the span of {V, V2}.
