Hi. Im looking for the formula to calculate the orthogonal projection of w onto the subspace spanned by u and v. Where W,U,V are vectors

    would that be the cross product of u and v?

    or rather, if they exist all inthe same subspace and are orthogonal; then wouldnt the dot products betweenthem be zero?

    The vectors themselves are as follows u = 1 over the square root of 2 [-1] [ 0] [1] v = 1 over the square root of 6 [1

    v = 1 over the square root of 6 [1 ] [-2] [1] w = [2] [1] [-3]

    There is a formula for orthogonal projection but it is usually used between two vectors, you would have to figure out how to use it with a third. For example orthogonal projection of v on u is [(v dot u)/||u||^2]multiplied by vector u
