Find the inverse of M, showing the steps. What is the result of M * M−1? Let V = [A B C] and W = [ D E F]. In the textbook, the dot product V • W involves an angle, alpha (α). How do you calculate alpha for this example? Let V = [A B C]. Find the cross product V • V. What can you conclude from this result?
