Compute the dot product for the equation, Mathematics

Assignment Help:

Compute the dot product for each of the subsequent equation

 (a) v = 5i - 8j , w = i + 2j

 (b) a = (0, 3, -7) , b = (2, 3,1)

Solution

(a) v • w = 5 -16 = -11

(b)  a • b = 0 + 9 = 2

Not much more to do with these other than use the formula.
