SUPER CONFUSING linear algebra question :) 1. The problem statement, all variables and given/known data I have attached a picture of the question with a solution. 3. The attempt at a solution Well... First i found the parametric equation of the vector L... Yeah... So even looking at the solution I am confused. I get the conversion that they made to rad/s but the steps after that blow my mind :|. What does omega mean and also why did they multiply by (1,1,1) and then took the cross product of this point and the direction of the rod? I want to get through this step by step. Thank you!!
