Alright so I am trying to find the projection matrix for the subspace spanned by the vectors(adsbygoogle = window.adsbygoogle || []).push({});

[1] and [2]

[-1] [0]

[1] [1]

I actually have the solution to the problem, it is ...

P = [ 5 1 2 ]

(1/6) [1 5 -2]

[2 -2 2]

Every formula I have found is not for two vectors but a vector and a matrix or something else. I found the formula P = A(A^{T}A)^{-1}A^{T}but that makes no sense for what A could be since I'm given two vectors and not a matrix. I feel like I'm missing something simple.

PLEASE help!!!!

Thanks
