I've attached the question to this post. The answer is false but why is it not considered the orthogonal projection?(adsbygoogle = window.adsbygoogle || []).push({});

##

A = \begin{bmatrix}

0 & 1 \\

0 & 0

\end{bmatrix}

##

##

B = \begin{bmatrix}

x \\

y

\end{bmatrix}

##

##

AB = \begin{bmatrix}

y \\

0

\end{bmatrix}

##

Is AB not providing the orthogonal projection? Is my matrix multiplication incorrect?
