The dot product of u with itself is 12. What is the magnitude of u?

A 24
B 12
C 2sqrt6
D 2sqrt3

How would you solve this, what is the formlua?

1 answer

a ⋅ b = a * b * cos(Θ) ... Θ is the angle between a and b

u ⋅ u = u * u * cos(0) ... the angle between u and itself is zero

u ⋅ u = u^2 = 12 ... solve for u
