[tex]T:R^{2}->R^{2}[/tex] projection transformation on X-axes parallel to the

line

[tex]y=-\sqrt{3}x[/tex]

find the representative matrices of T{*} by B=\{(1,0),(0,1)\} basis

how i tried:

i understood that the x axes stayed the same but the y axes turned

into

[tex]y=-\sqrt{3}x[/tex]

our T takes some vector and returns only the new x part with respect

to the new y axes.

any guidanse?
