1. Given the following 3 vectors, all of which lie in the horizontal plane, (see attachment for list of vectors), find:
(b) 1) A?B 2) B?A
(c) 1) A*B 2) B*A

For the example
A · B = |A| |B| cos ( A - B) = 3 × 5 cos -20°, cos -20° is not equal to cos(20),
Then A · B=3*5*0.9397=14.1.
The calculator uses radian of the angle instead of degree.
a. Given the following ...
