Homework Statement
I know the title is misleading but what I am asking is how I can get this matrix
x1cosθ-x2sinθ
x1sinθ+x2cosθ
to the matrix multiplication form
cosθ -sinθ | x1
sinθ cosθ | x2
where
A=
cosθ -sinθ
sinθ cosθ
x=
x1
x2
Is there a good method to do this or do I have to find it by eye-balling it?
