Find the dot product of u and v.
u= (−7,−1,8) ,v= (0,8,2)
a. 10
b. (0, -8, 16)
c. -24
d. 8
e. (-7, 7, 10)
Find u × v. u= (5,6,2) ,v=( −8,−4,2)
a. (-40, 4, 40)
b. (20, -26, 28)
c. (20, 26, 28)
d. -12
e. -60
Ok, Alan, you're right. I've got something confused.
Find u × v.u= (5,6,2) ,v=( −8,−4,2)
The dot product is a scalar Omi.
u.v = -7*0 + (-1)*8 + 8*2 → 8
.
