Homework Statement
Hey guys, I'm not sure if this bit is relevant but the first part of the question is... 'The diagram shows a triangle with vertices O, A(1,2) , B (0,2). The question I need help with is 'Each of the following matricies represents a rotation about the origin, Find the angle and direction of rotation in each case'
(1/2 -[tex]\sqrt{3}[/tex]/2)
([tex]\sqrt{3}[/tex]/2 1/2)
Imagine its one big set of brackets around the above matrix not 2 smaller ones :)
Homework Equations
I'm also not sure whether these are of relivance but x' = ax + cy and y' = bx + dy
also I have the matrix
cos[tex]\theta[/tex] -sin[tex]\theta[/tex]
sin[tex]\theta[/tex] cos[tex]\theta[/tex]
The Attempt at a Solution
I have been messing about with this for a while attemting to sub in co ordinates to the x' equations and y' equations but I feel I am getting nowhere. I would appreciate any help.
Thanks in advance guys
