Best ResponseYou've already chosen the best response.0Reduce v to a unit vector, v1=<3/5,4/5> Then premultiply by the rotation matrix \[\left[\begin{matrix}\cos(\theta) & \sin(\theta) \\ \sin(\theta) & \cos(\theta)\end{matrix}\right]\] to get the rotated vectors using \( \theta = \pi/3 or \pi/3 \).
