Part a what is the correct value or theta? Part b why does other formula give the wrong answer ?

8) Consider two vectors A and B where: A = -6.00 1 + 3.00 j + 3.00 k B - 6.00 2 - 8.00 1 + 4.00 k If we want to find the angle between these two vectors, we have two possible options: we can use the magnitude of the dot product, or the magnitude of the cross product. A . B = AB cos(0) A x B = AB sin (0) However, these approaches give conflicting answers for the value of 0. a) What is the correct value of theta? b) Why does the other formula give the wrong
