Let w = Find the projection of w on space V.
I've already found the span of
I worked out the projection matrix i.e. to be 3x3 matrix where
However i dont now where to bring w into the problem
Ooops sorry my bad, multiplied wrong
I wasn't saying the single row matrix was a 3x3 matrix... i was simply saying that i used the single row matrix to calculate the projection matrix (a 3x3) matrix using the formula
As my latex knowledge is still poor, it would have taken me too long to write out the 3x3 matrix...
Anyways thanks for pointing out my error in part 1 of the question
