Learning goal: to understand the rules for computing dot products. let vectors a=(2,1,−4), b=(−3,0,1), and c=(−1,−1,2). part a -
miv72 [106K]
For this case we have the following vectors:
 a = (2,1, -4)&#10;&#10;b = (- 3,0,1)&#10;&#10;c = (- 1, -1,2)
 The dot product of two vectors is a scalar.
 The point product consists of multiplying component by component and then adding the result of the multiplication of each component.
 For the product point of the vectors a and b we have:
 a.b = (2,1, -4). (- 3,0,1)&#10;&#10;a.b = (2) (- 3) + (1) (0) + (-4) (1)&#10;&#10;a.b = - 6 + 0 - 4&#10;&#10;a.b = - 10
 Answer:
 
The product point of the vectors a and b is: 
 
a.b = - 10
