Hi, I'm having some difficulty with this problem. I need to project a point in R2 to the line x2 = x1 (sqrt(3)) and then rotate it 30 degrees clockwise.
I believe the 2x2 matrix to map it is just
sqrt(3) 0
0 1
and to rotate a vector clockwise as opposed to counter clockwise I think is
cosx sinx
-sinx cosx
I could be wrong about these 2 matrices. Is there anyway to merge the two? Do I multiply them? Thanks.
