Hi, if i want to find a 3x3 matrix R which represents a rotation of Pi/6 around the axis of rotation v(vector)={1, 2, 3}. how can i find it?

Are you saying that your axis is along a vector that starts at the origin of the coordinate system and has its tip at the point (x,y,z)=(1,2,3)? And is your rotation direction clockwise or counterclockwise as viewed from the perspective of (0,0,0)?

find 3x3 rotation matrix
Start by figuring out what the result of rotating
[0,0,1] [0,1,0] and [1,0,0] are. Once you've done that, you shouldn't have any trouble making hte matrix.
