3.3 Consider frames I = (0, e1, ez, e;) and A = (0, aj, a2, a3), where e3 = a3, as shown in Figure 3.35. Find the position of P with respect to O in the following coordinates: a. Cartesian coordinates in I , (x, y)I . b. Cartesian coordinates in A, (a1, a2)A. c. Polar coordinates in I , (r, 0) . d. Polar coordinates in A, (p, B)A. P a 3.1 O Figure 3.35 Problem 3.3
