Find the angle between the vectors a = (4, 2, -4) and b = (4, -3, 2).
SOLUTION Since
lal = 42 + 22 + (-4)2 =
and
[b] = V 42 + (-3)2 + 22 = V 29
and since
a. b = (4)( 14 ) + (2)(-3) + (-4)(2 )
we have from this corollary
COS = a. b |а|
|Ь| | 89 So the angle between a and b is as follows. (Round your final answer to two decimal places.) 0 = cos-10 29 89 x rad
