Find the orthogonal projection of v ⃗=(-7, -9, -6, 10) onto he subspace W spanned by{(-2, -2, -3, 4),(-3, -1, 4, -2)}. I posted this question to my instructor: "I have tried to use the calculation (v*u1)/(u1*u1)+(v*u2)/(u2*u2) and my result is [-223/55 -823/165 -1658/165 1954/165]" and got this reply: "You can only use the dot product formula if the basis vectors are orthogonal. In this case, they aren't."
