You are given two vectors A = (a, a, 0) and B = (b. -b, 0). The format for entering a row vector is as a list of variables enclosed by double square brackets, as in [x, y, z], for example. Calculate the directions (unit vectors) A and B. Enter responses using a for a, b for b. The absolute value function of u is entered abs (u). A = B x You are given two vectors A = (a, a, 0) and B = (b. -b, 0). The format for entering a row vector is as a list of variables enclosed by double square brackets, as in [x, y, z], for example.
